A man of any age range, who is deemed emotionally unavailable, often charming, and can only relate to women or men on a sexual level. He can be gay or straight, but his MO is having sex with many diverse women or men, if gay, and never quite committing to any of them. He can also be referred to as a "Player." This man is emotionally immature and has not grown out of the adolescent stage of sexual lust. He may also be a man who people think of as straight laced and good. He can be single or married. He can be an overt manwhore, or a downlow manwhore.
Tiger Woods is a true down low Manwhore, as he has slept with many women in the same time period, but never committed to any of them, and he was married. No one would have thought of him nor did anyone imagine how many women he had sex with until it was discovered one November eve.
A Manwhore is a male that has several key attributes. A typically young (18-25)male who dresses in designer clothing, carries multiple cellphones, has become a master of manipulating women, and makes it his personal mission to sleep with as many different women as possible qualifies as a manwhore. He also has virtually no emmotional attachment to any of his victims. The reputaion of manwhore makes gaining new potential victims somewhat difficult, so most manwhores are forced to switch territories and stomping grounds frequently. However, even in familair enviornments, many manwhores can continue to get laid by playing the "im misunderstood, or "Im just pissed and acting out over a bad breakup" card. A true master in both deception and cunning, a manwhore is any "good girls" worst nightmare come true.
"Oh god, we need to hide Jenny, that boy is a Manwhore"
A sexually active, promiscuous, younger man who often wears alot of flashy jewelery, has greased down, or spiked up hair and keeps a 'chicktionary'. He is well known at most health clinics and may have an STD named after him in his honour. He knows many girls but will often mix up or forget thier names. He will commonly have one or more illegitimate children (though not always, especially in the amateur stage) and his relation with other men is often strained, due to past encounters with girlfriends or wives.
"He slept with your girlfriend's best friend and her sister, and her cousin at the same party! What a man whore!"
