Cheesetooth is a condition which affects mostly only redhead/gingerkids. It is named for the plaque covering one's teeth giving an appearance of a thin layer of yellow cheese. It is most easily noticed on pale-skinned subjects due to the strong contrast between their skin and teeth. They usually smoke cigarettes way too much as well. Also used as an insult to an annoying ginger kid.
