Poker in Prison?

[Roopster]

Think that is part of poker where going all in takes on a whole new meaning. Shoving on bubba could leave you with stack issues. I'll stay with the confines of the "zoo" here and leave the pokey poker to those blind stealers.

looks like a bunch of jibberish to me..best guess is some kind of prison sex reference..not every joint is an episode of OZ
