FAIL

Of all the mutilations of the English language that have surfaced on the Internet, the abuse of the word "fail" would surely count as one of the very worst. The word "fail" was originally a verb, so grammatically correct use would be "I am worried that I am going to fail the test." However, its usage has changed over the years, as internet users of various web forums began using it as a noun, referring to something as being "full of fail," as an adjective, such as saying, "This is fail," or even as a general exclamation of disgust by saying quite simply, "FAIL."
