An argument between two or more stubborn
people (or groups of
people) over trivial facts or insignificant historical events. The situation often will slowly degenerate into a loud spastic game of cards being played into the wee hours of the evening, never actually resolving the initial disagreement.
On rare occasions the opposite
may happen, beginning with the card game and ending with the argument.
I took the
wife and kids over to
Grandpa's this weekend, but after
dinner a Manweiler broke out, and we might never get invited back.
