Full on narcissistic behavior. He will hunt for prey that he knows he can manipulate because that prey/ she is naive and likes the boy enough to let him treat her with total carelessness of her feelings. He won't give her any validation of what his intentions are.

He will sweet talk her into believing that he actually wants to get to know her and hangout, but he is on a mission for one thing only. Sex. When she tells him that that kind of treatment is disrespectful, he turns the situation around being unaware or in denial of that kind of treatment and makes it more her problem. She won't get a simple apology because he has no empathy or care to. She will hear from him again and the fuckboy will manipulate her into believing that he really does care and that she is cute sweet and fun to hang out with, but never takes her out.... ever. It repeats over and over again for a while with the hope he will change. She may get validation of his uninterest by seeing him with a girl, that the prey didn't know about, that he actually is interested in. He won't tell you about this girl because the fuckboy wants to keep the prey around for sex and backup because he likes the pussy, not her personally. This makes the prey feel used, and weirded out with a bruised ego. This selfish behavior will exist in a man at any age. If she lets the fuckboy get away with it for too long, then it's also more of a personal problem that she needs help with.
Jen: he doesn't really care to get to know me but the sex is absolutely amazing making it hard for me to let go and get attached
Kim: if he doesn't care about you and only wants sex he is a typical fuckboy.

Jen: he'll change
Kim: get over it, you are wasting your time if you're looking for something more. time to move on dumbass

A fuckboy is a weakass dude who ain’t shit.
The guy who will go around calling women “thirsty hoes” but like 30 profile pictures in a row and comment “hot” because he thinks somehow it’ll get him laid.
The guy who calls girls sluts but goes around begging for nudes out of fucking nowhere.
The guy who sends unrequested dick pics with no context to women he’s barely spoken to.
The guy who regularly uses phrases like “bros before hoes”
The guy whose idea of flirting is “what would u do if i was there right now lol”
The guy who will call you a prude if you dont want to fuck anyone, but call you a slut if you want to fuck someone who isnt him.
The guy who will disrespect you and try and get with you in the same breath.
The guy who tries to text you even when he already has a girl
The guy who continues to hit on you even when you’ve said no
The kind of guy you have to lie about having a boyfriend to in order to get him to leave you alone.
The guy who will tell you “you’re not like the other girls” like that’s a compliment because he doesn’t have any respect for them.
The guy who will tell you “my exes were all crazy” even though you know them to be totally fine, kind, measured people.
A fuckboy is a guy who will tell you “guys don’t like it when you -” and try to shame you because of your weight, hair, style, makeup or anything else that you do in order to express yourself because in their tiny fuckboy minds you only exist to attract them.
"Dylan is a real fuckboy."

"Yeah I liked this guy but then he started pulling this fuckboy crap so I stopped texting him back"

What a fuckboy, asked for a girl's nudes after 5 minutes into the conversation.

a boy around their teenage years--between thirteen and twenty-five. they play with a girls' feelings and are notorious womanizers. they are also called Casanova and playboy.
generally, they are:

-privileged
-popular
-arrogant
-ask for nudes
-pretend they're interested
-masters at ghosting

this is for the girls if you like a fuckboy, this is a note to all of y'all. this is what you will be thought of if you try to go after a fuckboy. i would personally not go after one

this is how they think: if you are straightforward and show interest, you come off as too aggressive. if you are shy and waiting for them to make a move, then you are a tease and perpetuating gender stereotypes. if you want to screw you’re a slut if you don’t then you’re a prude. if you have a sense of style you’re a basic bitch. if you don’t then you’re not cool. if you initiate flirting you’re thirsty. if you don’t then they won’t talk to you. if you put on makeup you’re insecure. if you don’t then you’re ugly. if you want a relationship you’re boring and asking for too much. if you just want to hookup then you’re a hoe. if you show that you care about their wellbeing you’re trying too hard. if you don’t then you’re a bitch. if you want them to take care of you you’re incapable. if you can take care of yourself you are an aggressive feminist. if you don’t catch feelings and reject them then you’re a tease. if you catch feelings, then i would say you lose because the fuckboy won't.
Person A: Oh my God, did you see Michael last night with that girl? Even though he just broke up with Ella?

Person B: I don't know why he's your friend, he's such a fuckboy.

An overconfident ass who will lead a girl on just to let her down. Sometimes later apologizes only to say "send nudes" once the girl has welcomed him back into her trust. Boys like this will pretend to genuinely care one minute, and be emotionless the next. He is the definition of 'mixed signals'. Do NOT fall for his charms. Typically will call you baby girl and say cute things to get his claws on your emotions. If a girl tries to stand up to him he will likely deny everything and turn it around on the girl, making her feel stupid. Boys like this are egotistical assholes who can not be trusted and are hard to get rid of because they know all the right things to say.
Sierna: "He is so sweet to me and takes me out, but tells me not to catch feelings.. why does he do this to me?"
Payton: "He is a fuckboy Sierna! He's playing games, do not let him break your heart!!"

Get the fuckboy mug.
An immature, worthless boy who plays with your heart and feelings just so he can get his dick wet but then leaves you in the dirt for another girl and messes her up to. They will never stop, they were born to break hearts
"Collin is such a fuckboy, he told me he wanted to be with me but then he ended up fucking Rachel. I really regret loosing my virginity to that piece of shit
