In any video game, being beaten, in any division of game (firefight,
round, etc.), by a newb by a
large margin, or being defeated by one of the least powerful weapons in the game when you have clearly
superior weaponry.
Playing
Halo 2 while you have the sword and are defeated by someone with a needler.
A long time
player being defeated by their friend who has never
played before.
Even more so when a combination of the two.
