A great fear for other gamers is when a Shit Kid develops interests for other games, but fear not. If you encounter a Shit Kid online simply Mute or Block the player and you should be fine.

PS. Please note that thanks to the sharp and squeaky voice of a Shit Kid, may cause serious damage to your ears and if not treated right will cause your sense of hearing to decrease.

A person whom one can relate to shit for more than one reason, such as their skin or hair is the color of shit, they always talk about shit, or always have to take a shit.

When lil kids some were around grade 7 who just walk around, thinking their cool shit because there not in highschool yet and they don't know how brutal life is. Usually very cocky fucking kids that you just wanna pound their faces in.
