A chronic disease, in which a chemical imbalance located between the testicles and brain cause the affected male to act and think in a distorted and perverted way. No one knows the exact cause of Fuckboy Syndrome, but it is said to be both genetic and conditioned. If this disease is left to manifest, it will consume the fuckboys life and actions. How to tell if your dealing with a fuckboy? Ever heard "bros before hoes" "wanna come over and watch netflix?' "shes crazy" "send me a pic?" .. hes probably a fuckboy. If your dealing with one, or have someone in your life that shows symptoms : uncontrollably liking and commenting on girls pics, wearing douchy white sunglasses, and being extremely cocky and self righteous. You should proceed with caution. There is no known cure yet, but educating the population is a good start.

An acquired disease that results in perpetual immaturity and disrespect towards most women. Common signs and symptoms may include but are not limited to: no communication skills, emotional infancy, binge drinking most weekends, cheap/ keeps tabs on who pays for what, constant wandering eye, will sleep with whatever, and refusal to grow up and act like the adult that they should be. A grown boy with fuckboy syndrome will occasionally date a woman, let her trust him, let her believe he's different, all the while knowing he's incapable and unwilling to do what it takes to be a man, and break her heart. She's heartbroken and he moves on to his next challenge(s).
I heard Jill's boyfriend is seen on every dating site there is?!?

Yeah, they broke up two days ago. He's got fuckboy syndrome so bad... he's working on banging three trolls this weekend. Bet he's telling them they're so hardworking and strong... I give each of them a few weeks max.
