This warm up came from Bridie Connell, and she got it from her English teacher as a kid in NZ.
It’s a rap:
Group: Who’s the baddest gangsta (whoot, whoot), I’m the baddest gangsta (oh shit)
Single person: I’m the baddest gangsta because (lame thing, like I brush my teeth after every meal)
Group: oh yeah
be very rap-like. pass it around the circle. no need to rhyme or anything.
