Tossing Parmesan

The act of spreading cocaine about the outer extremities of one's anús while another individual proceeds to snort it. Derived from the term tossing salad due to the locality of the action and the parmesan like consistency of the aforementioned narcotic. Can be shortened to "tossin' parm."

Guy 1: It's so snowy in here but I'm so bored of snorting it off of the table.
Guy 2: I know! Let's try Tossing Parmesan!

Guy 1: Sounds good to me! *proceeds to lower pantaloons*
