We all know what tacky is...
Animal prints, hot shorts, platforms, bright nauseating colors, your grandmothers table cloth.
Tacknasty steps it up even more.
Tacknasty combines everything nasty in one.

Zebra platforms, hot pink hot shorts, and a leopard print tank top.
It can also be any type of person that can light up a room with their tan, seems dirty, wears lots of makeup and is over all tacky.
