Funny birthday messages to send to a friend: A collection of laugh-out-loud jokes and example phrases (1–10)
Only ◯ years left until the average life expectancy! Congratulations!NEW!
In today’s Japan, where the aging rate is rising year by year, average life expectancy is also increasing annually.
In 2025, the average life expectancy for Japanese people was reportedly 81.09 years for men and 87.14 years for women.
Here’s a humor-filled message that plays on that average life expectancy: “Only ◯ years left until the average lifespan! Congratulations!” Instead of celebrating one’s current age, it celebrates the number of years remaining until the average lifespan.
It’s an unusual kind of congratulatory message that might make you burst out laughing.
It’s the kind of funny message you can send precisely because you’re close friends.
Today, exactly ◯◯◯◯◯ seconds after you were born into this world. Happy birthday!NEW!
You probably don’t know how many seconds have passed since you were born, right? But once someone mentions it, you get curious—and I bet many people would love to find out.
So why not use a site that calculates how many days, hours, minutes, and seconds have passed since your birth, and send this message along with it? It’s touching that someone would go out of their way to look it up for you, and above all, it’s genuinely surprising to realize that so much time has passed.
It’ll surely become an unforgettable, special celebration!
I thought about a present, but you don’t need one since you already have the best friend—me—right?NEW!
Here’s a message recommended for anyone who struggles every year to choose a birthday present for a friend: “You already have the best friend ever—me—so you don’t need a birthday present, right?” Having a friend who celebrates your birthday is a happiness that can’t be replaced by any gift.
The funny part is that you’re the one saying it yourself.
You might even get a reply like, “That’s true, but… can’t I still get a present?” It’s a message that lets you enjoy the conversation that follows, too.
You’ve climbed yet another step on the staircase to adulthood… there’s no going back down, though.
Messages with a touch of black humor can be fun, too.
One I’d like to introduce is: “Looks like you’ve climbed another step on the staircase to adulthood… though there’s no way back down.” This works not only for younger people, but also with relatively older recipients—it’s easy for them to quip back with something like, “I’ve been an adult for ages.” You could also use this message as a springboard to broaden the conversation around the theme of a “staircase to adulthood.”
Bakeries around the world will surely be emptied for the ◯◯ celebrations. Before they sell out, I’ll buy some too—want to eat together?NEW!
When it comes to birthday celebrations, it’s all about the birthday cake! Many people prepare a cake for a close friend’s special day.
Here’s a fun, classic cake-themed message for such an occasion: cakes sell out at bakeries all over the world because everyone’s celebrating your friend.
It carries the meaning that so many people are sending their best wishes.
And by saying, “I’ll buy one before they’re all gone—let’s share it together,” you can also express your desire to celebrate the special day together.
It might make them chuckle, but it’s a message filled with genuine care for the person.
Today, ◯◯ is the star! Starting tomorrow you’ll go back to being just regular friends, but today, become a princess and have as much fun as you can!NEW!
The day we were born into this world, each of us was the protagonist, welcomed with blessings from many people.
And every birthday we celebrate each year is a special day when anyone can be the star! The message is that on such a day, we hope you’ll have fun pretending to be a princess or a prince.
The added line, “But starting tomorrow, we’ll go back to being ordinary friends,” is brimming with humor, isn’t it? No matter how old you get, it’s always wonderful to be celebrated on your birthday.
Being called the protagonist or a princess can feel a bit over the top and a little embarrassing, but realizing you have friends who wish for you to have a birthday that joyful is the kind of message that’s sure to make you feel happy.
Cheers to this day you descended to Earth just to meet me.NEW!
Let’s deliver a smile to your dear friend with a slightly cheesy birthday message! A toast to “the day you descended to Earth” just to “meet me”—you can’t help wanting to make a snarky comeback to every single line, right? Words you’d never normally use with a friend, messages so over-the-top and corny they give you a bit of the chills—the kind that’ll make the recipient burst out laughing.
But if that birthday message is aimed at you, you’d feel how hard they tried to make you laugh, and it would make you happy.
How about celebrating this year with some uncharacteristically suave lines?
Age is just a number. Help yourself to unlimited cake and laughter!NEW!
Birthday messages often end up sounding the same every year, don’t they? Here’s one recommendation for times like that.
Many people can’t help wondering how old someone’s turning, but try sending a positive message that says, “Let’s just laugh, eat, and live without worrying about age.” In reality, people who feel bound by age tend to limit themselves, thinking, “I’m already X years old.” While it’s important not to push yourself physically, it’d be nice to always keep a young heart.
I’m glad we can still celebrate birthdays at this age. We’re both aging and getting more wrinkles at the same time, though.NEW!
Being able to stay close with friends the same age is one of life’s treasures.
Here’s a message I’d love to give to those easygoing friends you can truly relax around.
By acknowledging that we’ve grown older together in a good way, it feels like our bond will deepen even more.
This message also carries the hope that we’ll keep having fun together, sometimes helping and encouraging each other, and continue living long lives side by side.
Wouldn’t it be wonderful if we could keep weaving joyful times together from here on out?
Too many candles—have the fire truck on standby!NEW!
This is a playful message that jokes about age using the number of candles on a cake.
Normally, you wouldn’t imagine a fire breaking out from just a few decorative candles, right? But what happens as the number grows? With each passing year, the candles increase, and if you actually put that many on the cake and light them, you can’t help but worry, “Won’t this start a fire? Is it safe?” This message humorously portrays that idea using an ambulance—the kind of hero that would come to the rescue in such a moment—to add a fun, lighthearted twist.
