One who initiates the act of fellatio; a fucking
cocksucker (the kind that engages in
oral sex, not an asshole, a buttknocker, a bungsnoipe, an asshaberdasher, etc.).
This term is usually used to describe faggots, but it can also be used to describe a very despicable
person.

2: Osama bin Laden was such a penus
vacuum; I'm so glad that the Navy Seals
hosed him down!!!
