The most ridicolous genre of music ever, which the world would probably be a much better place without. Originaly used in the 80s as a term for side-projects or 2nd bands of ex-members of well known hardcore bands, it has now become a stupid new fad defining a genre of music which has already been defined millions of times as pop punk, emo, hardcore, fattycore, etc.
A: Hey you want a bacon sandwhich?
B: Bacon sandwhich? wtfzzz, it's all about corned beef now yo.
Replace Bacon sandwhich with emo, and corned beef with post hardcore.
You get ma drift?
