Manheimers 

A mental deterioration in the male brain that can occur at any time when a man tries to recall things a lady likes or needs, this may be due to generalized degeneration of the brain maybe he’s born with it. It is the most common cause of premature senility.

Me : Every time I ask my dad for a cherry Pepsi he leaves and comes back with a cherry coke.

Friend: that’s because your dad has manheimers.

manhammer 

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.
