A variation of the infamous snowball;

When having anal sex, you ejaculate into your partner's anus, suck the semen/feces mix into your mouth, and spit it back into their mouth.
I convinced my girl to give me a snowball but, since she doesn't like the taste of her own shit, she wasn't ready to take it to the next level with the New York Snowball.
