fuckboy 

A young very immature male who has no idea of what a real man is. Despite being raised primarily by single mothers they have no respect for women at all and will say or do anything to get their dicks wet. They love older women with kids but complain about the kids being present in their own homes when they want to fuck the hard working stressed out lady they are pursuing. Fuckboys have no respect for anyones feelings and will betray you once they've said all the right things to earn your trust, they disappear for months at a time then pop up out of nowhere, act like they care, tell you they miss you and then ask for anal sex and a blow job in the same breath. Immediately following any acts of sex they ignore phone calls, don't text, then won't even bother to say thanks or goodbye. A fuckboy will even behave this way towards the people who have genuinely looked out for him and had his back even when nobody else has. Thats why he's so hated and despised but a real fuckboy won't care nothing about that because his dick reached its target by faking the nice guy or making people feel sorry for him.

Karbiel is a true fuckboy he sees everything that lady has on her plate and he's over there trying to fuck her but won't even answer her phone calls

Fuckboy 

A word used by feminists and SJW's for men who disagree with them, or they disagree with. Possibly stemmed from its use as a male version of the word "slut", though the word was mainly used in this way prisons, referring to weak young men who could be raped and wouldn't fight back.

"That guy who says he isn't a feminist is such a fuckboy"
"That guy who won't fuck me cause I'm fat and ugly, even though I'm still beautiful is such a fuckboy"
"That guy I simply don't like is a fuckboy"
