Get the Fuck boymug. A teenager usually 7th - 10th grade that can move on to girl to girl in less than a day. Is all talk over text but face to face can't do shit. Thinks every girl likes him. Thinks every time he hangs out with a girl they are trying to suck his dick. First day ever talking to some one will ask for nudes aka 20 questions ( do not play )

Get the Fuck boymug. A guy that thinks he has swag. Will usually be seen wearing Jordans or Nikes, sporting snap backs, and those soccer Adidas pants, along with saggy jeans, and Diamond or Obey brand t-shirts. They flirt with a lot of girls and play them to get them to sleep with them. Usually will go after the easier fuck girls. They are disgusting human waste.
Did you see that fuck boy? He totally sent a nude to Ashley while he was dating Courtney. What a fuck boy!
