Energizer Sauce

Energizer Sauce : The sometimes frothy, usually slimy, amalgam of lubricant, stray fecal matter, and ejaculate that leaks out of the receiving partner's anus after a session of anal intercourse. So named for the energizer bunny that keeps going and going.

Girlfriend: "Why didn't you stop after you came?"

Me: " Because there was Energizer Sauce for days!"
