Another term for a "boom boom room" or somewhere where there is an assortment of women and sexual activities going on and on an ongoing basis. A strip club could be considered a "poon palace" as well as a brothel, an after hours spot or a party house where there are known to be lots of hedonistic events on a regular.
"oh you done turned this motel into yo own lil poon palace, huh patna?"
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.

FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
