A comeback of the "yo' mama" genre. If you really think about its implications, it's rather insulting.
Steve: "Yo' mama blows so hard she started Hurricane Katrina tryin' to put out the candles on her birthday cake."
Tony: "Awwww sheeit..."
Derek: "All right."
Steve: "Yo' brother so broke and stupid he went to the Nickelback concert to try to get 5 cents."
Tony: "Diggity damn..."
Derek: "Oh yeah?"
Steve: "Yeah. And I heard your sister got a summer job breedin' hound dogs!"
Tony: "Ooh...that hurts."
Derek: "Well I'm your dad."
Steve: "What?"
Derek: "Yeah, just got the paternity test results. I remember that night. I was in line right behind the St. John's basketball team."
Tony: "Ooooooh snap! You just got served, son."
