More formally thought of a punch in the groin/testicle area, this is incorrect, as it is in fact a punch on the buttock (or both buttocks). Spunch is a combo of the words 'Spank' and 'Punch'. It is not sexual, it is ment to be harmful. It can be given to either a male or female, but only in private.

I just spunched someone.
My buttocks hurt from that extreme spunching
