When the female stuffs her finger into her box, then pulls her finger out and wipes it across your lip.

Similar to the dirty sanchez.
I stuck my finger down my wife's butt crack and wiped it across her lip and yelled "DIRTY SANCHEZ!", which she responded by sticking her finger in her box then wiping it on my lip and yelling "DIRTY SANDY!"

A footjob from a female with gnarled up feet. Usually with bunions, corns and hammer toes.

While almost repugnant, you get off on them anyway.
I got a dirty Sandi from that prostitute. Years of streetwalking have beat up her old dogs but I still got a nut.

I was expecting that hottie to have sexy feet but that was not the case, those toes looked like curly fries. But hey I still got a dirty Sandi and creamed them piggies up good.
