Someone who talks to a girl and makes them feel really special and kisses them and then goes back to their ex just to play her and then lead her on again and acts like a douchebag to everyone and can't understand that you need to pick one girl and not two.
Jess: "Did you hear about that guy I was talking to?"
Sarah: "Yeah, he's such a fuckboy. Don't trust him. I heard he kissed a girl and took his ex back."

Get the fuckboymug. 
Get the Fuckboymug. A guy that ditches his homies for day one to go hang out with some bitches the nigga isn’t even friends with. Shit to be honest your homies gotta be your day ones because their the ones that have your back. You can trust any bitches in these streets. Also some guy that ignores and doesn’t talk to any of his friends just to hang out with some bullshit girls.

Get the Fuckboymug. Adjective.
An adjective which describes a male human which uses girls.
A fuckboy uses girls' trust to receive 'pics' or to have sexual intercourse.
When they get what they want (sex) he will tell everyone and leave you. However, if he doesn't get what he wants (sex) he will leave you. Either way fuckboys leave you.
Fuckboys come in groups. They hang out with other fuckboys. This is called a 'fuckboy pack'.
Once a fuckboy, always a fuckboy!
