flailmaster 

Brian. 'Nuff said.
One who flails uncontrollably when objects are thrown at them or in their general direction. Item needs not actually be thrown.

Brian sure is a flailmaster!

To suicide in Super Smash Bros.

Inspired by a wolf using his final smash, only to fall through the stage and die with his landmaster.

"You just failmastered."

"FAILMASTER!"
