Sloppy taint 

A vagina with extra long unsymmetrical labias that are covered with an oily, greasy white residue. Normally noticed after extensive sweating from having sexual intercourse.

For instance, "Maurice only speaks to females or transgenders known for having sloppy taints."

The moist, fat undercarriage of a saggy old woman that slaps against itself during any form of movement

I love eating ham and mustard out of a slappy taint.
