Get the fail mug.
An amazing word that can sum up almost any bad situation in a single syllable.

A bad grade.
Sam: Urgh, my girlfriend just broke up with me.
Soph: Fail!

I hope I don't get an F on the test.

1: To not achieve one's goals.
2: To recieve a grade of less than 60/100 on a test.
3: A word which has become an instant giveaway for stupid teenage fucks who think they are clever because they say things like "EPIC FAIL" or "YOU FAIL". Originally, these and other stupid phrases incorporating the word "fail" were given birth within internet cesspots such as 4chan, but they have rapidly found acceptance among the adolescent population as the new, cool thing to say.
It is likely to become another pseudo-intellectual word popularized by the internet- further examples including words such as existentialism.
1: I wanted to fuck her in the ass, but even after I said that she'd do it if she really loved me, she said no. I failed.

2: At the DMV I scored a 15/100 on the Alcohol and Substance Abuse test. Suffice to say, I failed.

3: "You've never seen Donnie Darko? YOU FAIL."
"You don't like Napolean Dynamite? YOU FAIL."
"You think My Chemical Romance sucks the fucking sack?
YOU FAIL."
"My mom made me clean my room? FAIL."
"Eat my brocolli and carrots? I DON'T WANT TO. YOU AND
MOM ARE MADE OF FAIL."

Get the FAIL mug.
A word that has become just as overused as the word "random." It originally meant "lack of success" but over-use of the term has caused it to loose meaning.
Stop using the word "fail"! It's not cool, it's not funny, and it's not original.

What internet morons say when they lose a moronic internet argument.
"The Earth revolves around the Sun."

"No!"

"Yes."

"Fail!"

adjective
1)a: describing any noun or event as having failed; b: the state of being a failure.

2)An internet meme that has become more commonplace in "RL" amongst those of the video game/internet culture.

The use of fail and its amusement are derived from video games out of the common "game over" screens or "mission failure" notifications. Often this is used in redundancy to create a sense of irony: Fail ____ is fail: in which case any noun is thus being identified by the adjective and described by it.
-"God that tank in VOA sucked ass..."
-"Fail DK is fail!"
