Someone who is completely awesome, cool, and pwning for one second but degenerates into a worthless sniveling noob the next.
I.E. ichigo's second fight with grimmjow.
CoD reference:
P1: Didn't P5 go 50 kills - 3 deaths last round?
P2: Yeah, but he's 3-25 this game.
P3: It's because he's a masked ichigo.
P4: His KD is 3-35 now, and its only been 2 minutes since we started talking.
P5: I hate you all...
