look up any word, like cunt:
 
1.
Possessing and/or exuding the quality of manliness.

2.
Vanity - to the excess - in a man. Man + vanity = manity
If your man can't help himself from looking at his reflection in every shiny surface, from a store window to the new wax job on the car, he suffers from a severe case of manity.
