Acronym for Crab On Booty Syndrome. This syndrome occurs most often in high school and college students who haven't slept or gotten what they want over an extended period of time. Symptoms include
irritability, hunger, the inability to co-operate with others, pouting, whining, frowning (in this case we will refer to it as an
upside down smile), and a general distaste for the other people who inhabit
planet earth.
