"Time was, fail was simply a verb that denoted being unsuccessful or falling short of expectations. It made occasional forays into nounhood, in fixed expressions like without fail and no-fail. That all started to change in certain online subcultures about six years ago. In July 2003, a contributor to Urbandictionary.com noted that fail could be used as an interjection “when one disapproves of something,” giving the example: “You actually bought that? FAIL.” This punchy stand-alone fail most likely originated as a shortened form of “You fail” or, more fully, “You fail it,” the taunting “game over” message in the late-’90s Japanese video game Blazing Star, notorious for its fractured English." - Shannon Jiménez
