Tater Eater
A large woman (often from the deep south), whose round and lumpy shape can be attributed to a diet of heavy sugars and starches (with an emphasis on home cooking, i.e meat and potatoes). Often seen in sedentary jobs like cashier, bank teller, or fast food employee. (Tater is southern slang for potato.)
That girl has never missed a meal, and she looks it; she's a damn tater eater.
