Fear, The
An urgent, uncontrollable need to use the restroom, coupled with the anxiety that there is not enough time to make it to said restroom. The term originated when Psycho Mike related a story wherein he took care of business on his parents’ lawn because he didn’t think he would make it inside. Tales of The Fear also surrounded the later fascination with Hot Cheetos and their undesirable side effects.
Go to urbandictionary.com and vote this term up. Not sure why, but it has become my obsession.
