NAS-tard (adj.) - A person who watches cars turn left for three hours.
"Cletus has lost quite a few brain cells since he began watching stock car racing, he's a first-class NAStard."
A neologism (made up word) combining "nasty" and "bastardization". Used to convey disgust at a silly or inappropriate running together of two or more words.
Ironically, "nastardization" is a nastardization in and of itself.
