Fuckboys are often bitchy and controlling. They typical are aged 12-25, or 56. They wear Eddie Munster platform shoes. They typical are soul sucking gingers and tend to make love to their Harley's. A guy who will tell a female what they need to hear to just receive pleasure filled evenings only to end up with a flaccid ass dick. They actually blame the female for him failing to get his bubble gum dick up when its in his full control. They will marry you ONLY on their birthday and make sure to buy you a gift you hate the most but they adore. Will ressure you that is what your most favorite fruit is. Again a Fuckboy will AGAIN on your birthday make YOU cook his favorite meal and knowingly make you think that it is yours. Then again will buy the same fruit and expect sex again with a flaccid ass dick. Even after 34 years of marriage and children.

A fuck boy, is a grown ass man, that acts like a boy. He fucks everyone he can, including himself. A dog has more common sense.

A boy who sincerely only cares about himself. He reels you in with his charming looks just to leave your ass for another bitch another day. But the catch is he keeps coming back.
