bogart v.

drug slang, "to keep a joint in your mouth," dangling from the lip like Humphrey Bogart's cigarette in the old movies, instead of passing it on, by 1968, in "Don't Bogart That Joint" by Fraternity of Man. The word also was used 1960s with notions of "get something by intimidation, be a tough guy" (again with reference to the actor and the characters he typically played). Sixties slang, but the notion isn't new; in old drinking slang, Captain Cork was "a man slow in passing the bottle."
