Scup -- Means scroll up, you missed something. The phrase first appeared in live twitch chats which viewers used to signify that the host missed a message the viewer wanted the host to see.
Viewer: What are you doing later?
Host: *Doesn't read*
Viewer: Scup
Host: *Scrolls up and reads chat*
Host: Oh yeah I'm going to be doing stuff later
Super Cunt. Unbelievable Pussy.
A woman who is mean to her core, rude in every situation, a complete bitch to everyone she meets. But she got that pussy that could take you to Mars faster than Elon.
Wow, that woman is unbearable but I can’t resist when she shoots me that “You up?” text, total SCUP.
