A fuckniteboy is very similar to a fuckboy, except this person also plays fortnite avidly. This person can be seen posting stats onto their stories on Instagram and Snapchat. They are disliked by almost everyone, including their parents, who are now wishing they considered an abortion.
Did you see that Fuckniteboy's story on Instagram? Why does he think people care about this shit?
