Absurd Vinyl Prank Stickers for Your Friends’ Cars

Nothing brings people together like a harmless prank… especially one that results in your best friend unknowingly driving around with a sticker that proudly declares, “I POOPED MY PANTS!”

In this project, I’ll show you how I designed, cut, and applied a set of ridiculously embarrassing vinyl stickers—perfect for secretly slapping onto your friends’ vehicles. These bold, cartoonish designs are easy to make, easy to apply, and devastating to find on your bumper three hours too late.

Let’s begin the descent into prankster greatness.

Vinyl cutter (Cricut, Silhouette, etc.)

Adhesive matte vinyl (I used orange)

Transfer tape

Weeding tool

Cutting mat

Laptop with design software (Cricut Design Space, Illustrator, etc.)

Scissors or craft knife

A dangerous amount of confidence

I started in my design software (Inkscape) and made each sticker big, bold, and impossible to ignore. Some examples I created:

1. “MEOW (I talk to animals)”
2. “I STEAL candy from babies”
3. “I ❤️ TO FART!”
4. “ATTENTION!!! im potty training!”
5. “OOPS… i pooped my pants!”
6. “Im a moron!”
7. “FERDA is my middle name”

Keep the fonts chunky, high-contrast, and slightly chaotic. If people don’t squint and go “Wait… WHAT?” then the sticker isn’t done yet.

Load your vinyl onto the cutting mat matte-side up.

Send each design to your vinyl cutter and let it do the magic.

Pro tip: Don’t walk away. The moment you do, the machine will decide it wants to eat your vinyl like a hungry goat.

This is the oddly satisfying part.

Use your weeding tool to remove all the excess vinyl around your letters. It should look crisp and clean—like a professionally printed confession of embarrassment.

If the sticker says “I POOPED MY PANTS,” remember: craftsmanship matters.

Cut a piece of transfer tape to fit and smooth it over the sticker.

Use a scraper or a credit card to press it down firmly. You want the letters to stick to the tape cleanly so they’ll go onto your victim—uh, friend’s—car effortlessly.

Now for the best part.

When your friend isn’t looking (or is distracted by something shiny), gently apply the sticker to their car bumper or back window.

Use a quick rub over the surface, peel off the transfer tape, and walk away casually—like you didn’t just ruin their reputation at the next stoplight.

Pro tip: Don’t laugh until you’re at least 10 feet away.

Take pictures. Take videos. Capture their moment of discovery.

These stickers deserve to live forever in your group chat.

nce you start making these, you won’t want to stop.

Create themed packs like:
