So when you trendys ascribe the word "epic" to banal things like the Tron poster (not even the entire movie, just the poster), and children's games like "duck duck goose," you cheapen the word and water it down so it just becomes a sound you make, like a grunt when you approve of something. And it's not just used for approval, it's also used to describe minor disappointments, like having to restart a DVD because it skipped. Now every minor inconvenience is an "EPIC FAIL." And if it's cool, it's not just cool but an "EPIC WIN." And for the record, fail is a verb, and is something you do, like fail at English. The act of failing is "failure," and is a noun. People can be failures, but they can't be "fails." That doesn't make sense. So when you say "epic fail," what you really mean is "epic failure."
