"Knocked up" is slang for "Impregnating"

Though it is generally used negatively, in certain "ghetto" settings, it is a compliment to tell a girl her boyfriend knocked you up. No one is sure why, but many believe it is a compliment for implying that said boyfriend is attractive/sexually potent.
"You're flyboy got me knocked up/impregnated me"
"Thanks, girl! He is a looker!"

To knock up a guy means to fuck him in his asshole and have a cumgasm.
Matt always wants to knock up my asshole trying to make me pregnant because he says it would be fun to have a little skippy-boy running around, but I told him it doesn't work that way!
