A psychological state in which one believes they are the best at any subject, and are the hottest shit on the earth. One who has a sheneequa complex invariably suffers from unwarranted self importance, and is indeed, not the hot shit that the presume their self to be. The word originates from the various "Sheneequas" who personify the word. If you have never encountered a sheneequa just take a trip to Detroit. The complex it self refers to when one is not actually a sheneequa, yet acts like one. Those who have this terrible condition will usually raise their voice for no apparent reason, finger snapping may follow, and some unintelligent babble. It infects 90% of the female teenage population.
