Tilted

As apposed to centered or balanced - Tilted is when your anger starts getting the best of you and becomes detrimental to your focus, thereby resulting in underperforming.

The angrier you get, the more tilted you become, resulting in a relative negative impact on performance.

When you are tilted, your basically being nudged off balance(your best game) from anger.

-Yo, why are you so garbage tonight?
-I'm so tilted, this guy keeps drone striking me even if I'm alone in the woods and no where near the objective.
