Debris resulting from aggressive homosexual anal intercourse with someone who failed to cleanse themselves thoroughly before getting ass-rammed. Can be found on a condom in the case of protected sex, on the penile shaft and glans in the case of unprotected sex, and in the pubic hair in both instances. Usually consists of fecal matter, but can sometimes include fragments of poorly digested foods such as corn kernels and peanuts.
