2. A way of masturbating yourself that try to simulate the sensation of having your penis into a vagina. Much like the well known apple pie, but instead of having your dick into an apple pie, which don't require a lot of setup, you have to put it in a whole jar of warm smegma cheese, which can be really hard and complex to get.
