pnp specialist
A person who is for hire to administer party drugs to men who want to pnp. Usually the drug of choice is meth and it is administered via i.v., since many persons can't do it themself. After everyone has been injected, then the "PnP Specialist" is usually gifted with a dose to join in the fun as well.
The PnP Specialist came highly recommended and made everyone in the hotel room very comfortable which is why we insisted he join our PnP soiree.
