going over niagara falls
Holding your pee to the point where it becomes painful so that you don't have to leave a position where someone you're on a date with has just made a move. Alternately, doing this during a new fling during "Netflix and Chill". But then the "going over" is pissing your pants.
Oh man the date was going great but then she started going over niagara falls and it was awkward.
