ReTard 

ReTard n. Portmanteu of "Republican" and "retard". Someone who, intoxicated by an assumption about being knowlegable and right about politics and economics, forgets that they need to get actual real ordinary people to support them if their agenda is to be advanced. Often but not always middle class, easily led and with poor insight to society's problems, and naive about the mechanics of politics and utterly ignorant about how power actually works.

The Tea Party is utterly ReTarded

retard tingles 

(pl. n., used with sing. or pl. verb): a spontaneous condition characterized by extreme discomfort & experienced by people in awkward situations; retard tingles occur in embarrassing circumstances including but not limited to: inappropriate laughter at ethnic jokes while person from said ethnic group is present, calling your teacher ‘mom’, walking in on your boss in the bathroom, and scenarios in most Ben Stiller movies.

Ending a phone conversation with ‘I love you’ when you are not talking to your significant other can cause severe retard tingles for the person on the other line.

Mike Myers exhibited symptoms of retard tingles - shifty eyes, nervousness, blushing - when Kanye West said “George Bush hates black people” during a telethon on live TV.

Your fart was so loud that the entire movie theater got the retard tingles!
