1. Adj. An expression used to state that a situation is fine. Seldom used on proper nouns. He is dope, is not often said.
Example: It's all dope.
2. Adj. An expression used to state that a friend's possession is awesome.
Example: Your car is dope!
3. Adj. An expression used to state that an unfortunate circumstance is displeasing.
Example: This weather is dope! Now I can't go boarding! (A negative intonation is placed heavily on the word 'dope', and it is almost spat.)
Originates from the slang for marijuana. So, be careful not to use it in anyway where it would be mistaken for a noun. Such as: Psst...Hey buddy, ya got any dope?
4. Adj. When used in the negative, it's to say that something isn't right in the moral respect.
Example: Don't do drugs. It's not dope man. (I must admit, seeing where this word comes from, this particular sentence can be rather ambiguous. So let me give it to you straight. Don't do drugs. It's not cool man.)
