A variation of ponytail hairstyle that is frequently worn by trashy, white chocolate, or redneck women. The base of the ponytail is tied up on top of their head (as opposed to the back), with the rest of the hair falling down in one greasy-looking section; sometimes a braid.
Brandine put her hair up in a trashytail so everyone would be able to see the "Duck Dynasty" quote on the back of her t-shirt.
