The guys who worked on the original movie said "Kill her mommy" in a microphone and echoed the first syllables, so it's supposed to sound like Kikiki mamama... But in some movies, like Jason takes Manhattan, it just sounds like they re-recorded it as "Ch".
That's what happen when little Jay hears about premarital sex and booze! I guess he's a republican or something (just kidding XD). And as for Bubba, I'm not quite sure he's even aware of what's going on right now.
Thanks about the comment on the new look! It'll keep getting better. And about the poor little Fred, he have Jay his share of trouble before! But really, I'm not gonna favor anyone, and for the course of the entire comic, I'll do my best to keep them on roughly equal grounds.
