It might seem irrational, but I genuinely can't stand when grown ass men use "uwu so cute'n'sad" anime girl reaction images in their threads on 4chan.
Specifically on /r9k/, which I realize is a shithole no matter what, but still.
There is something specifically annoying about this type of poster. And they NEVER outright state they're male, always beating around the bush.
It's fucking pathetic.
