- A flooskin is where a guy stretches his ball sack and a girls takes a shot of any hard liquor off his ball sack while it's stretched out.
- A flooskin could also mean any word you want it to be.
"Hey darryl, can I have a flooskin?"
"Sure, lemme stretch my ball sack and grab the whiskey"

Or..
"Hey can I borrow a flooskin, I only got to hooskins left?"
