Dime

From Rap Dictionary

noun

dime

1. Ten dollar bag of marijuana. Due to price variations the price may actually be higher for the same bag.
2. "To drop a bomb", to fink. The term has probably descended from the time when phone calls were 10 cents, and is related to the notion of moving gossip quickly, as one would drop a dime into the phone to make a call. Often "drop a dime". Another possible origin is the ten years by which a jail sentence might be reduced in return for finking.
3. A pretty woman; ten as in a rating on a woman's beauty. "Niggaz say you a 3 I think you a dime" -- D-12 (U R The One) [1]
4. Also known for shooting up as doing 10 mils in liquid.
5. Slang for an assist in basketball, as in 'to drop a dime'. Origin is unknown, but it could possibly come from the fact that good shooters are a 'dime a dozen', while good passers are harder to find.
