Quite simply a vagina. This comes from how it fits around you like a squishy mitten.
How'd your date go? I beat the squishmitten up all night.

Another name for the vagina. Of course getting its name from the soft squishy feeling, and mitten.... well because things go in there.
After I was done with her squish-mitten, I came in her face.
