Help me figure out this song!
 

OK... way back in the day, when I was but a wee lass who didn't yet know the glory of Electronica, I had a thing for rap. This was between the years of 1999-2001, at boarding school.

Anyway, there was this song that I really liked and saw the video for it once. I have heard it about three times my entire life. I *think* it involved Mystical in some way. I remember in the video, for the chorus whomever was singing would cross forearms and say "X!" and then whichever part of the chorus.

I know this isn't a lot to go on, but it's been driving me crazy for about four years cause I really wanna hear it again, and I cannot remember it. Accquiring it once I know what it is won't be a problem... I just don't remember what it is!!!
