The guy who your girlfriend is jealous of because you spend more time with him than you do with her. He is one of your most loyal friends and will not hesitate to back you up in any situation.
That guy at the party who's dressed to impress your girlfriend, complete with popped collar and suave handbook, he will attempt to sweep every girl at the party off her feet with his pseudo-charm.
A condescending term used towards a male who tires to project his masculinity when trying to find a sexual partner, however comes off vain and unsuccessful.
