Colonnaise

The creamy amalgam of semen and feces compounded together during anal sex. Known to ooze from the rectum and coat the man shaft upon withdrawal.

Rachel was dripping the colonnaise last night.

I had a thin patina of colonnaise on my cock after drilling that whore in the ass.

I won’t do anal. I don’t like colonnaise.
