Hat-'tard

noun
Blending the noun 'hat' with the slang noun contraction of 'retard'. 1. A person who wears a baseball cap with the bill turned sideways, backward or otherwise in the wrong place for ridiculous, transitory social status rather than practicality. 2. A wanna-be gang member or rapper. See also wigger, See also eminem

Eric thinks he's a bad-ass Crip gangbanger because he wars his Cubs cap turned left. Don't tell him but he's really just a stupid wanna-be hat-'tard.

E-tard 

One who is still caught in the clutches of a constant state of MDMA use whenever they attend any type of nite club, dance or electronic event. Can be spotted easliy huddled in corners with others, grinding teeth, giving all their cash to the bartender, talking not just to much, but saying to much and spreading false love to people they hardly know. Plural = E-Tards

The Nick Warren show would have been great if the E-Tards had not had it on lock down the whole nite.
