look up any word, like b4nny:
 
1.
The act of stealing a negligible amount of drugs from your friend's stash, in hopes that it will go unnoticed. Usually motivated by desperation, not spite or ill-will.
"Mike, this bag looks a little low. Did you pinch something out of here?"
"Aw man, it wasn't that much. Just a Gentleman's Grip."
