The most disgusting thing you can think of that is still a human being. A person who is a Grimey-Grime can only bath once a trimester cycle after they have pretended to have intercourse. Their hair is always sex hair, because they can't afford shampoo. They speak of drinking with parents and going to jail. Overall anyone who baths rarely and has a rat nest for hair.
Oh, she sits next to this disgusting kid in Earth and Space.
Omg is that him?
The one that has a rat nest for hair, and sneezed all over the keyboards in the Photography room?

He is a total Grimey-Grime
