Muffed

Raging at something in an over the top manner. Such as a video game.

Usually involves a response that is not appropriate for the situation.

Swearing and cursing is a must, as well as using the phrase "I'm sick of this shit"

Man, he was really muffed.

He really muffed out
He's totally muffed
Don't get muffed at me
