The use of a mental disability to get off easy or cover your ass when things get hairy. Coined from Carlos Mencia's use of "dee dee dee" to refer to retarded people. Also known as the "tard defense" or "idiot immunity". The catch is you have to be smart enough to figure it out.
I'm able to be 10 minutes late for nearly all my classes because I can use my autism as a dee-dee-deefense. Works every time.
