another name for the male sexual organ; only if it is used to hammer the bitches. If it is used in a slow, loving caressing style, then it is not a manhammer but a "bitch toy".
I was laying the pipe to some skank last night. As I went for the power stroke my manhammer slipped out and I jammed it in her mud-hole.
When you are having a threesome with two guys and a chick and one is getting head while the other is giving anal and the third is in her vagina. and simultaneosly jizz at the same time.
Oh man me tommy, jake, and adam gave courtney an alsakan manhammer last night
