A descriptive word, usually negitive directed towards anyone who's adopted this MTV disposible lifestyle as a culture.
If you wear a XXXXL white t-shirt, and you're not a teenage girl at a slumber party, that's gnuck. If you ARE a teenage girl at a slumber party and you have the words cute, sexy, or grab me printed acorss the ass of your sweats, that's gnuck. If you put 22 inch spinning rims on a minivan, that's gnuck. If you're a white kid with corn rows, that's gnuck. If you're a 30 year old rapper living in the basement of your parents, that's gnuck.
