Black Sheep (1996)

Revealing mistake: Watch the scene where they're headbanging and the tape keeps going out. You can see where they splice the scene in because the trees change in the background instantly.

Mike: I'm just dandy, I got a bowl of chocolate pudding in my underpants.
Steve: We didn't have any pudding in there buddy.

Trivia: When Chris Farley is playing football with the kids and they're in the huddle, he says the play is "32 belly option on 2, on 2". In Tommy Boy when Chris and Rob Lowe go cow tipping, Chris gets down and says, "It's a 32 belly option on 2, on 2".

Question: When Chris Farley's character it talking for his brother at the concert, he sees the black guys he was smoking weed with and tells the audience to "kill whitey" which stuns the audience into silence. I have heard this phrase before. What does it mean?
