A special needs boy who pretends to be normal by cussing, using social media, and hanging out with normal kids (but mainly the cutest girls he sees). In reality not even the ugliest girls want him. He gets made fun of by the hot girls due to his habits.
Girl 1: Hey, you see that special needs kid right there with us?
Fuckboy: Ha, hey!
Girl 2: Why are you here, fuckboy? Where are your own friends at???
Fuckboy: Ha, hey!
Girl 2: Why are you here, fuckboy? Where are your own friends at???
