I have used /asp/ since the /sp/ days (9 years) and have literally no idea who Bitchtits or Ojama are.

it’s never been explained, never been talked about in depth. I dont even think either of them are real people, its just a word that gets thrown around by autists toward people they dont like as a catch all phrase for a dumbass. Just one day it randomly started being said and acted like it has some big backstory . it doesn’t.
