Funny prank ideas for my boyfriend. Cute mischief.

We’re introducing some prank ideas to play on your boyfriend!

These days, more and more couples are extending their playfulness by pulling pranks and tricks on each other.

When it comes to pranks, some can be extreme—leading to breakups or making him angry—but the ones we’ve gathered here are mostly lighthearted, the kind that end in laughter and bring you closer together.

If you’re worried he might get mad when you prank him, use these as a reference and try having fun together.

Pranks that make him panic might be a good option for couples who feel things have been a bit dull lately.

If your boyfriend “hates being deceived,” it’s better to avoid pranks altogether!

Funny prank ideas for your boyfriend. Cute pranks (21–30)

Period pain prank

[Prank] What will a boyfriend do if his girlfriend is suffering from menstrual cramps?
Period pain prank

Menstrual cramps are a kind of pain and fatigue that men can’t really understand, right? This prank is about seeing how a boyfriend reacts when his girlfriend seems to be suffering from period pain.

It does feel a bit bad to trick someone like that, but when he treats you gently or cancels plans for you, it really makes you feel loved, doesn’t it?

Vertical acrostic LINE prank

[#][*][Prank] Will Love-chan and Aipi notice the acrostic LINE message!? [Experiment]
Vertical acrostic LINE prank

When it comes to LINE pranks, lyric pranks are the classic, but since everyone knows them, they often get figured out quickly.

That’s when the “vertical reading LINE prank” comes in handy! With this prank, you send a hidden message using the first character of each line.

For example, if you send two lines like “Sukiyaki tabeta, kino” (I ate sukiyaki, yesterday), the first characters spell out “suki” (I like you) when read vertically.

How about sending your boyfriend a seemingly grumpy or mean set of messages to make him panic, only to reveal a hidden message like “I love you” or “Always together”?

playing dead

[PV] My Wife Pretends to Be Dead Every Time I Come Home. [Hobonichi-P]
playing dead

A blog became a hot topic about a wife who is always “playing dead” when her husband comes home.

Its humor drew so much attention that it was adapted into a live-action version and even made into a movie.

How about surprising him with a similar fun prank? If it’s too realistic it might give him a real scare, so it may be better to keep it a bit softer and go for something on the funny side.

clear ramen

[Prank] I suddenly served “transparent ramen” made with clear soy sauce, and their sense of taste completely broke lol
clear ramen

This is a transparent ramen made mainly with transparent ingredients such as clear soy sauce, clear dashi, and clear glass noodles.

The finished dish looks like cloudy hot water with glass noodles sunk in it—hardly an appetizing appearance—but when you eat it, it mysteriously tastes like regular shoyu ramen.

Because the flavor that spreads across your tongue differs from what the appearance suggests, your brain gets confused even if you know how it’s made.

Since it’s about enjoying tasty food, it’s something everyone present can have fun with, and it’s also an interesting prank that lets you examine the relationship between appearance and taste.

Pretend to forget their birthday and then celebrate it in a big way

I pretended to forget my best friend's birthday and then threw a big surprise celebration lol
Pretend to forget their birthday and then celebrate it in a big way

When it comes to big events for couples, birthdays come to mind.

Many people probably take it for granted that they’ll be celebrated, but how about pretending to forget—even if you had planned a date or to meet that day? If the room is secretly set up for a party, the disappointment will flip to excitement all at once, which might make it feel like an emotional bargain (lol).

Going full menhera and causing a wild rampage prank

[Crying Hard] When I suddenly acted like a menhera in front of my overly kind boyfriend, it led to a moving ending...
Going full menhera and causing a wild rampage prank

If your usually cheerful, bubbly girlfriend suddenly turns all menhera and starts sinking into gloom saying, “I’m sick of everything,” how would your boyfriend react? Try voicing increasingly menhera-like anxieties—“My hairstyle looks weird, right?” “My face isn’t cute anyway.” “Hey, you’re cheating on me, aren’t you?”—and watch how he responds! If you say things like this all the time, he might not take you seriously, but if a girlfriend who rarely voices her insecurities pulls this surprise, he’ll probably do his best to calm her down!

A non-lover replied on LINE! Will you notice?

[Concern] For those worried about slow replies on LINE, read this
A non-lover replied on LINE! Will you notice?

I think many couples casually chat on LINE every day, not because they have something specific to discuss, but just to make small talk.

But if someone other than the girlfriend were the one replying to those casual messages, would the boyfriend notice? Even if they usually text all the time, it’s hard to tell through written messages—and he’d never imagine that someone else is replying, right? Still, there’s that vague sense of something being off.

The prank is to see how he picks up on that feeling and how he expresses it.
