A fuck boy is a little bitch who messes with girls. He's obviously hot but is not as pretty inside as in out. He fucks up girls by leading them on then fucking with other girls the next day. He can also maybe just make up shit about you to sound cool in front of friends *pussy* oops. This bitch deserves a kick in the fucking dick to get his nonsense straight!
