A fuckboy is someone who does shit that pisses the whole population off all the time. He will also lead on just for hookups, he says he's really into you but just doesn't want to deal with all the "relationship bullshit" just to fuck you. He thinks about himself and only himself all the time and pretends to be really nice. He also does really fucked up shit and then complains about people who do the same shit as him.
