Flirting comes in endless forms, from playful teasing at running club to playfully swiping someone’s hat at the playground. But one technique that’s recently gone viral on TikTok is the so-called “triangle method”—and no, it doesn’t involve whisking your crush away on a romantic getaway to the Pyramids of Giza (though that would probably work too, if you’ve got the budget for such grand romantic gestures).

Here’s everything you need to know about the triangle method, including how to try it yourself:

### What is the triangle method?
Imagine your crush’s face. (Seriously, picture it!) Now, think of their eyes as the top points of a triangle and their mouth as the bottom. Slowly move your gaze from one eye to the other, then down to their lips. There—you’ve got it!

### Why does the triangle method work?
When flirting, you want the other person to feel like you’re truly noticing them—their face, their voice, what makes them unique (without being weird, of course). The triangle method subtly shows you’re appreciating their attractiveness without being too obvious. And let’s be honest, making direct eye contact is always a good move.

### Is there any science behind it?
A 2024 speed-dating study found that people were more likely to choose partners they made more eye contact with. (No surprise—attractiveness played a role too.) While you don’t need the triangle method to lock eyes with someone, a quick glance at their lips—hinting at a kiss—can definitely add to the spark.

### Should I try it?
Why not? As an experiment, I tested it out on my partner (aka the only person in my living room). He definitely returned the intense eye contact. Did he notice my gaze drifting to his lips? Maybe not—but he did kiss me later. (Though that might’ve just been because I finally did the dishes.)
