When someone announces an "Epic Win" or "Epic Fail" that ends up being uninteresting, off subject, meaning-less or a let down. When you get excited to find out what the epic was, and are dissapointed so much you "ugh" out loud.
Bob: "Man! Epic fail today!!".... Harry: "omg dude, what happened?!!".....Bob: "I forgot to return that movie tonight on my way home!"....Harry: ".....ugh...(rolls eyes)" Epic Ugh.
