Santor-stash 

having anal sex with a girl, waiting for her to fall asleep, taking your finger and harvest her Santorum( the frothy mixture of fecal matter and anal lube) and planting it on her upper lip. Much like the popular "hitler stash" .

Girl: does it smell like Santorum in here?

Guy: I don't smell anything baby.
(Guy whispers to friend): dude I totally Santor-stashed her last night.
