acronym for "tasty little dish" which is used to describe the cuter or smaller girls of the girl variety. You can even use TLD out loud without girls knowing what you are talking about...unless they're smart of course...
GUY 1: "DAYYUMM check out that TLD, mang!!!"
GUY 2: "WOW I would rock that number ALL NIGHT!"
GUY 1: "oh.. i guess you can say that about your sister.."
