A body piercing on a male person, approximately at the pubic bone's most forward process.
The piercing is usually a larger subdermal or similar so that there is a 'mushroom head' or similar shape that makes contact with the clitoris during sexual intercourse positions where the male and female are face to face, and the males pubic bone makes contact with the female's clitoris.
Ineffective if the male does not shave his pubic region.
"That guy I met last night had a clithammer piercing. It was such an odd but exciting sensation!"
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
