Mushroom baton

The use of one's penis as a striking weapon. Preferable method is while it is erect. This will make a nice thud noise upon contact with one's face, forehead, cheek, chin, or nose.

The chicken head used too much teeth during oral so I smacked her with the mushroom baton. Left a nice welt on her cheek too.
