Coke that is cut on usually a wholesale level that is usually cut with procaine or benzocaine and mixed with acetone that is pressed with a large press machine to make it the coke into one solid piece to make it look like it might be uncut but people who truly seen lots of coke still can tell the difference.
Person one says "Yo I think this caine might be uncut because it is rock" Person 2 respond "nah man I can tell that it is repressed because it doesn't have that flaky glossy look."
In Philly a unofficial cab in the that usually takes you to drug spots. Sometimes the driver will wait outside of a subway and yell hack cab especially to people who look like their not from that hood because usually they are looking for drugs.
