The sticky stuff left on a penis after anal intercourse. Especially notorious is the "hot drilling mud", which comes if the recipient had spicy curry or other spicy food earlier.

Comes in heavy and light varieties, depending on diet.

Similar to santorum, but thicker and less frothy.
You should have had an enema, now I'm covered in drilling mud.
