Squirrel push
To dig in the anus of your partner with one's finger trying to dig out a piece of poop (similar to a squirrel digging into the ground looking for a nut). After digging out said piece of poop, the poop is then placed into the mouth of the digger to be carried around like a squirrel carrying a nut in it's mouth.
There's a bit of blood on my finger after 'squirrel pushing' her and now I can't get this taste out of my mouth.
