A term that is used to tell a hot ass girl what she needs to do to avoid getting fucked by you. Expressing your thoughts toward an incredibly sexy female.

This expression typically conjures a vision of the woman running with fuck me pumps clickity clacking on a dirty sidewalk to escape.
Damn, that bitch better run...cause she's gonna get Fucked!

Damn girl, you better run!

Better run girl...ya gonna get FUCKED!!

A sarcastic phrase that originated in a Steam review for Call of Duty Black Ops 3, when a game loads so slowly to the point where you assume someone who can't even run (Stephen Hawking) is faster than the loading time of the game.
John waited for his new game to load, and the game's loading time said it would finish in 3 days.
John: (Writing a negative review) Stephen Hawking runs better than this game.
