An explicitly, mostly heinous, shameless and always degrading beating or whomping..... whether sexual or not.
1. "Hey man, how'd the date go last night, did you get some action?"
"Of course, I gave that bitch a schnoopin'!"
2. "Did you watch the game lastnight?"
"Yeah we gave that team a schnoopin' without lube"
To have sexual relations of any kind, possibly in a covert and/or sketchy fashion.
I heard Megan was trying to schnoop Andrew.
They were schnooping each other last night on the mantel.
