Wondering if your Tinder match is your one true love? Their nickname can offer a pretty damn good guess, according to TikTok relationship expert Dani Coco.

The dating creator recently shared her new “nickname theory,” a hypothesis arguing that your crush’s unofficial moniker among your friends — and even their lack thereof — can serve as a tell-tale sign into the future of your romance.

“Nickname theory is the idea that the dumber the nickname you give the man you’re dating, the less you like him,” she said.

Though as Coco explained, the tradition of giving potential suitors a nickname stems from helping your pals stay up-to-date on your love life without remembering every last John, Jake, and James, this theory argues that the dumber the nickname, the less likely you are to spark a lasting romance.

“If on your first date, he told you his favorite kind of bagel is a plain bagel with cream cheese — a serial killer’s order — so you start calling him ‘plain bagel with cream cheese guy,’ it’s not that serious,” she explained. “You’re not gonna stand up on the altar one day and say ‘plain bagel with cream cheese guy when I first met you I knew that we’d be together in sickness and in health.’”

In other words, MidMan, Hot Gilbert Gottfried, and Daisy Duck Fetish Guy — all real, dumb nicknames of people I have had the (dis)pleasure of dating — will probably not end up as my S.O.

Meanwhile, men named after places or relevant information — i.e. calling a dude “beach guy” if you met during a beach day or dubbing him “gray convertible dude” because of his car — have a much more ambiguous prognosis than their inane counterparts.

“That kind of nickname means it is TBD,” Coco added. “You might like him, you could like him a little bit, it could go anywhere from here.”

But the gold standard of nickname theory, however, is not having a nickname at all.

“If you go on a date with a man and you start referring to him by his full, government name to your friends, you’re getting married,” she said. “Congrats on the wedding, when’s the date?”

So next time your best friend gushes about “Aperol Spritz guy” or “Greta Van Fleet man” ask her if she really sees herself saying “I Do” to a dude forever linked to a pretentious cocktail or a mediocre Led Zeppelin cover band.
