When a man has a hypothetical boner for another man. i.e. mancrush. This does not mean that the man is actually sexually attracted to men, just that if he were attracted to one, a certain man would be it.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.

When a person gets extra excited about a manly thing. Not in a sexual mannor but that intense.
