Another day, another viral trend TikTok, but unlike challenges that see participants eating food coloring or supergluing their lips, this one requires a partner, namely your partner.

Dubbed the "Naked Challenge", the prank sees people sneaking up on their naked partners. But don't get too excited. Name aside, the premise isn't as X-rated as you'd initially think, as there's no actual nudity thanks to the trend of capturing more funny facial reactions.

According to Know Your Meme, the Naked Challenge first went viral in late March thanks to a user from TikTok named @lindseybear1, who decided to break off her boyfriend Call of Duty game to fun results.

Since then, many other single couples have given the trend a shot. In fact, the Naked Challenge has become so popular that it's even inspired singles to attempt it with their pets, roommates, and parents, but try it at your own risk.
