A term used to describe any meal that one feels is
sub-par or bad tasting. This term has nothing to do with African-Americans (some think so because of the arguably derogatory nature of the word
nappy).
Grammatical rules are generally very relaxed with this word, as it can be used to describe a restraunt/eatery that serves food that one believes to be unsatisfactory.
Also, on occaision, this word can be used to describe
people (most often females) whom one may deem
fugly or aesthetically deficient. This useage of the word is debateable, as it would imply this person tastes bad, which may or may not be true.
Example 1 (food item): Ay man, don't buy the Jose Ole burritos from the lunch cart,
nappy meal.
Example 2 (restraunt): I aint never goin back to that chinese place down on East Main, that place is
nappy meal.
Example 3 (person): Ugh
dude, did you just say you thought Paris Hilton was hot? That bitch is nappy meal.
