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.
