Someone who doesn't give a flying fuck about anything but screwing girls. They almost always have the sides of their heads shaved about half an inch shorter than the rest of their hair, which is generally shorter and sticking straight up. They think that shitty rap music by shitty fucking artists is anywhere close to interesting, and they talk to anyone who says otherwise in rapidly changing pitches of voice. Literally all they'll do Throughout their life is ask a girl out, fuck her a few times, break her heart, and then blame it on her like a little cunt. They almost have no fucking muscle but they lift up their shirt like they don't have anything but soft flesh under it. You can usually spot a fuckboy by their disgustingly over-the-top hairstyles, ostrich strut, and autistic facial expressions. If you encounter a fuckboy, attempt to distance yourself from him by any means possible. Yes. I just assumed that the gender of fuckboys is male. Fucking sue me, feminazis.
Friend 1: Man holy shit, I can't believe she cheated on him for that fucker.
Friend 2: Yeah. He's such a fuck boy; I'm not helping her whore ass out of that shit when it goes arseways.

A fuck boi is that one 15 year old boy you have on facebook who posts selfies of himself pouting with more than one filter applied over the picture and gets way more like than he deserves.

Typically fuck bois have gelled quiffs, think that it is acceptable for a boy to pout in photos and frequently post selfies with their 'six pack' in full display.

They have over 100 likes on their profile picture because they have 2,000 girls as friends facebook and simultaneously flirt with them all, have smoked weed twice yet own HUF socks and post pictures of their Nikes on instagram with the heart eyes emoji as the caption.

Fuck bois often think that they are cool for bragging about having sex or getting drunk.
"this fuck boi needs to stop writing soppy paragraphs on my facebook newsfeed, everyone knows he's only doing it to get into the pants of one of the 2,000 girls he's friends with"

A fuck boy is a little bitch who messes with girls. He's obviously hot but is not as pretty inside as in out. He fucks up girls by leading them on then fucking with other girls the next day. He can also maybe just make up shit about you to sound cool in front of friends *pussy* oops. This bitch deserves a kick in the fucking dick to get his nonsense straight!
*fuck boy walks down the hall*
Girl 1: He's so hot but a total fuck boy ugh
Girl 2: agreed

How to spot a fuck boy:
-His Nike socks pulled up to his fuckin knees
-Nike sweaters all the damn time
-Most likely has the international fuck boy haircut (Shaved on the sides, long on the top)
His text messages include:
"Lol so wut would u if i was there ;)"
"send sum pics?"
"haha imagine if we had sex"
"lol so r u a virgin"

STAY AWAY FROM THEM. THEY WILL NEVER FIND THE CLITORIS. DONT SEND NUDES.
