look up any word, like blumpkin:
 
1.
1) {when about person} ugly, butters, disgusting
2) {when about thing, e.g. food} horrible, nasty
3) general negative word
Derived from the word dutty, meaning dirty
1) "Man that bitch is datty!"

2) Man 1: "Wanna go to the slug & Lettuce?"
Man 2: "Nah man, the food is datty there!"


*No offence to anybody who works, owns, likes or has ever seen a slug & lettuce, is only an example* :)
