someone who desperatly needs a brace but has oral hygene so bad they get rejected by the dentist. so their oral health deteriorates until they have 'Shredders' Yellow, misplaced, missing goofy teeth. they are immensly reselient yet badly decayed, they are useful and the build up of plaque has doubled up as a protective coating so they are virtually indestructable

Man: ew that bird opened that bottle with her teeth.
Woman: she must have shredders
