Wax and tax

An old fashioned way to say you will:

1. have sexual intercourse, or

2. beat, destroy or annihilate your friend, foe or stranger in a serious or joking way

"You're weak, see, I'm rough hardcore
And even be down to give you a rematch
After I wax and tax that butt" - Guru

Friend 1: Yo! turn it on Mortal kombat I've been practicing!
Friend 2: Please, you bout to get this work, I'm about to wax and tax dat ass
