Slang term for a way of using crystal methamphetamine. A needless syringe is taken and filled with a solution of meth, and insterted into the anus of a male (or female). The contents are then emptied into the anus, and the partner male inserts his penis into the receiving persons anus.
Justin jammed the syringe into Scott's ass, and after dumpin all da meth into him he fucked his ass all night long!
