A stumble-rumble is the result of having consumed a few too many and proceeding to kick the living shit out of another person or one's self due to irrationality.
Shirley got into a stumble-rumble with Bob at the karaoke bar because he sang their song with Sue-Ellen.
A stumble and rumble is an activity for gentlemen who engage in a game of Stumble Guys. The player who finishes in last place is required to watch the other guys whilst they view a porn video, strictly not being allowed to see the screen themselves. No self pleasuring is permitted at any time from any stumblers. The video must be stopped at the first sight of vaginal penetration.
We had a quiet one at the apartment last night, a few us played a quick stumble and rumble then went to bed.
