(v.) Occurs when selling drugs to a sketch person that you don't know, like, or care about. The seller will take out any amount for his/her own personal use and then sell the short sack to the square who probably doesn't have a scale anyway, so don't worry.
Dealer Man: "If niggas be talkin all stupid on the phone, i pinch his/her sack."

Jose:"That freshman with the hearing aid just asked me if i could get him an 8th of whacky tobbacky. Is he for real? "
Todd: "That dude looks like Mincus from Boy Meets World, you have to pinch his sack."
Jose: "Its a done deal."
