This is perhaps the most misunderstood insult for a male. A Manwhore is usually someone who spends his time with multiple girls for sex. Now, as I undestand it, such a person is a player; and should be respected by his fellow men. A man should never ever refer to his fellow men as a "manwhore" We shall refer to these people as "player", or "balla" or "omfg he's the most awesome cat ever"
I'm not a manwhore, I'm a girl farmer.
