a girl who has no girl friends and only hangs out with guys. Generally a slut.

The attractive hot girl who will go out with a good guy friend when he needs to look good at a party or other social event. Not an escort, but a friend.

When a guy likes a girl but the girl will only ever see the man as a friend

When a guy pulls such a bro move for his guy friend that he deserves a trophy for it.

A nice guy is the no-in between guy. He is either bald or so exceptionally hairy that he creates shade like a willow tree. He may be shaped like Baby Hughey or thinner than a crack whore (although he will neither use crack or be a whore since he's a nice guy.) In fact they are often virgins (naturally or born again) and volunteer time and funds to drug rehabiliation and other noteworthy programs. The nice guy may have impaired vision and wear thick glasses that create the highly undesirable affects of a funhouse mirror.Other nice guys may have excellent vision in their eyes that bulge, wander or cry frequently. The NICE GUY makes an excellent friend as he picks up tabs, earns trust, runs errands, rarely complains, watches chick flicks, rubs your feet, accepts collect calls, posts bail, and holds a steady job. He is however, unworthy of being kissed or touched in a romantic way - because you can treat the Nice guy anyway you wish and he will accept you with open arms. There is no need to praise, or show positive emotion or affection toward the nice guy... he's loyal as a pooch.

The pansy that has been raised to treat women with "respect" and "dignity" and feels obliged that the woman owes him a relationship in return. Most likely the girl will say, "You're a nice guy, etc..." and he will be relegated to puppy love flirting and countless hours of masturbation using his tears as lubrication. He will then become so pissed off, he will rant about how women don't see him for what he is and that all us bad boys get the women. Ultimately the nice guy will try to become a "bad boy" himself but just be made a fool of himself by girls that see him attempting to hide his insecurites, forcing him to revert back to his nice guy ways and the cycle starts all over again.

A hypothetical "ID card" that indicates that someone is a "real man". Used most often in a self-effacing manner when performing some supposedly "unmanly" deed, but occasionally used to mock another man (usually a close friend, said in jest) who has done or is doing such a deed.
