Brain Wreck 

A state wherein a person cannot comprehend the sheer magnitude of chaos or stupidity in a situation, causing their brains to undergo vapor lock as they try to come to grips with the enormity of the particular error.

"That guy was so stupid when he shot himself in the foot that it gave me a brain wreck!"
