smfwas 

Acronym for Super MotherFucking Weak Ass Shit (S.M.F.W.A.S). Pronounced Smiff-was.

Adjective, describes anything that is weak in nature and deemed to be pathetic, whether it be a choice someone makes or someone who is scrawny and needs to hit the weights.

Originated as W.A.S. but then the S.M.F. was added to imply even more weakness.

Hey Gibinator, go to the gym and lift, you scruffy smfwas n00b!
