So there's a couple things, the "friendzone" which does not exist, can mean different things. The definition I run with, because men are fuckboys, is that feeling when a person feels like they are owed sex because they were a shoulder to cry on or acted like a decent human. And yes, this is real, you may not act this way, no one cares.
Then there is the whole "a friend I liked rejected me, now I'm in the friendzone

" okay and? You two won't smash, move on. You two are friends, keep that shit. You don't have to want to smash all of your attractive friends
So yeah, the "friendzone" is fucking dumb.
