A GRWM (Get Ready With Me) video is where someone films themselves getting dressed, doing makeup, and talking through their routine. Pretty common on TikTok.

But here’s the thing: if you play one of those videos in reverse, it totally looks like some average Tiktoker is doing a slow, PG-rated striptease. She goes from fully put-together to in her undies, and if she throws in a little dance or spin (which they often do for flair), it just makes the whole thing look kind of suggestive. Once you notice it, you can’t stop seeing it.
