Smores

A sex act that can be completed solo or with a partner.

Solo: a man tucks his penis under his ballsack and ejaculates into his own butt crack while defecating, then squeezes his butt cheeks together mimicking a large pair of graham crackers.

With a partner: A man ejaculates into a partners butt crack while holding their butt cheeks together. The partner must be simultaneously defecating during the ejaculation to create a true smore.

Man, im sitting in dirty old smores right now.

Yo, I heard Joshua gave that chick a nasty smores last weekend.
