When a bull dyke doesn't quite have enough testosterone supplements to grow a real mustache so they get something tattooed above her (it's) lip. WARNING: These will usually be seen in conjunction with tear drop tattoos, notched eyebrows, and names tattooed on the neck.
some random word in spanish tattooed in old english lettering above the lip thus creating the Tatt-stache.
