Cat: A musician
Heavy cat: A really good musician
A hit: An engagement, a gig
Rectangle: A paycheck
Lizard: A burned-out GB cat who does the hit just to get his rectangle
Bobby!: A cue to start a James Brown song -- James Brown often spoke to his MC Bobby Byrd in song intros.
A double: Two gigs in one day (very common on popular dates)
Crossover: When a wedding spans the afternoon and evening on a popular date, thereby preventing the band from doing two gigs
You're doing good!: High praise for a fellow musician
