Women were pissed/jealous that men are considered a pimp, a player, and "the man" when he sleeps with a lot of women and get a lot of pussy. So women created this phrase out of anger. What women don't understand is that why this double-standard tips in our favor (men), is because men have to always do all the approaching and it takes more skill/talent for a man to get pussy, than it does for a woman to get dick. That's why we get props for getting pussy, and women get ridiculed for opening her legs 7 days a week. HAHA!
Joe: I slept with 5 different hot chicks over the past 2 weeks! I fuckin' rule!
Susan: You're such a man slut. I hate you.
a heterosexual male who has a girlfriend/fiance, dates 1 or more other women in addition to his significant other, and engages in sexual encounters both in person and online with still other women. furthermore, the man slut usually does not take proper "safe sex" precautions and will blame the females with which he engages for any std's or pregnancies which occur.
bobby, cliff, and boyd were such redneck white trash man sluts that to have sex with them and not catch something, you'd need industrial strength condoms and extra strength lysol w/bleach.
