the best, really really good, excellent
This sound is the joint. This music is the joint. The new CD -it's the joint. This joint is the joint.
In NYC in the 70's, the joint
meant that something was very good or the best. It could be just about anything.
Ex. 1. Yo, did you see that movie last night?
Yeah, it was the joint.
2. I heard Parliament last night. Tear the Roof of the Sucker is definitely the joint.
3. This pizza is the joint!!~
