The location of a single black, brown, or grey tooth located along the gumline usually surrounded by white teeth. Much like a lone tombstone, the spookytooth looks rotten and weathered. Offen referred to as a "dead tooth", the spookytooth generally only makes an appearance when a person smiles. They know it's there, you know it's there, yet they act like it doesn't exist if they don't smile.
Skankyspice looked so hot tonight until she smiled and that spookytooth scared me. She doesn't have a methmouth but I still can't bang her with that tooth staring at me.
