lol. In elementary school I literally had girls say "ew it's tactotown2142." when I walked by. The first time I confessed my feelings to a girl she literally started tearing up as if I'd deeply offended her, then briskly walked away and never spoke to me again. But I've also had plenty of interactions with girls where they weren't total bitches, but they still weren't sexually or romantically interested in me in the least. Though keep in mind I graduated HS in 2012 so tinder wasn't really a thing during HS so I imagine it's even worse for an incel now. But I'm 27 KHHV. Hardly a Fakecel.
Basically I learned pretty early on that If actually respond to their shittiness in kind, maybe by calling them an ugly bitch or something, rather than sheepishly enduring it, they're a lot less likely to keep stepping on you. Also my absolute worst bullying was from other dudes, and that was also based on my appearance.
