A person that is not a member of the "nerd" group or friends with them, but as soon as they hear about the wifi password getting out, they proceed to befriend all the nerds just to get the password. Tends to not have good grades and spends most of class and free going on their phone. Wifi fuckboys are prevalent in schools that change their network passwords frequently, resulting in said fuckboys to constantly bug the nerds for new password. If you're a nerd you probably hate them because as soon as password changes, they wont leave you alone until they can get on the wifi again.
