noooo….Mr. P… BAD BOY is not the one who is having “tattoo and another piercing, drinks copious amounts of vodka thro' his nose, verbally abuses women and treats them like crap, cheats on them and generally makes them feel worthless, cos thats what they want”.. nooo... Not at all… You have described some jerk…:)
Bad guy might be very gentle, very polite, very passionate, very sweet..he makes gal feel GOOD about herself… but there is always some “dark side”, some mystery in this guy… he is not as clear and understandable as the “Good One”… you don’t own him like you can “own” a “good boy”… he is not boring… you never know what to expect... he is strong enough to say NO even if you want to hear YES… Not necessary that he is cheating.. but because of this “dark side”, and this “mystery”, it gives you feelings that he MIGHT, which makes him even more desirable..
Bad Guy is a Player, and therefore is always interesting…
Good Boy is translucent.. and therefore is boring…
..by the way, I would say, the same things apply to the girls…
