Used to describe a total and complete
retard, P.O.H. standing for Pants-On-
Head. This is the highest level of idiocy one can achieve, and use of the term epic fail while calling said moron out is encouraged, because it is the only term known to
man that can do justice to the stupidity of the action. It's that bad.
Moron: I'll be making 100,000,000,000 dollars when i patent my solar powered
flashlight! Haha!
Guy 1: Are you frigging POH
retarded?
Guy 2: He definitely is; Epic Fail.
