another word for an insanely awesome song or jam session.
In the movie "pick of destiny" JB and KAGE ( tenacious D) challenge Satan to a rock off, and if they lose KAGE must go to hell and be Satans little bitch.
"God dammit Kage,
he gonna make you his sex slave,
your gonna gargle Mayonnaise
unless we bust a massive monster mamajam"
