When a much more superior men's college basketball team loses to an underdog team, and causes much embarrassment and tears for the losing team. George Mason being the most notable example when they made it to the final four in 2006.
Friend 1: Did you catch that basketball game last night?

Friend 2: Yeah I'm surprised that the upset occurred.

Friend 1: Yeah they totally got George Masoned.
