A sexual maneuver performed after girl-on-top copulation.

The slimy, viscous fluid left behind after a female has dragged her camel tizzy across a surface such as your sheets or face.

When a man becomes intimately involved with a woman he will then after sex produce Slug Trails which are also known as Cum Stains.

Where a woman rides your face and leaves a magnificent trail of goo across it. It feels like a huge, Amazonian giant jungle slug has crawled round your face.

The residue left on bed linens after a man ejaculates, cleans up the bulk of the semen, and then sleeps naked, allowing the remaining liquid occupying the dead volume of his reproductive organs to leak out slowly. The man's flaccid penis is then remarkably analogous to a slug, leaving ooze trails as it squirms about.
