What the f#@$% is a redrack and a pup?

I couldn't stay away! Joburg at night ...off to some equipment houses now. All the grip and electric terms are all different so I have NO IDEA what I'm getting right now. They have completely different terms, so I'm going to see if someone at the house can teach me the terms. Damn, just when I thought I knew what a platypus was...I hope I see a leopard later on today...
