A twat-tac is a non existent vaginal oder remover. Sometimes it is used to refer to Vagisil Rephresh, and other vaginal oder medications.
I was about to go down on this hot chick that I brought home from the bar but when I removed her panties I realized that she really really needed a twat-tac. The smell was unbearable.
