Epic

When something is epic it means it's AMAZING! So when you say that flip was epic, you're saying the flip was cool (times forty-seven though). Epic does NOT mean any of the following: Lame, awkward, stupid, or disgusting. Epic, while a slang word, should at least be used properly at all times, because it's epic. 

P.S. You're all epic if you think I'm right.

P.S.S. If you don't think I'm right, just go away....forever.
