Reply #18: noun: That frothy mixture...

... of lube and fecal matter that is sometimes the byproduct of anal sex.

Man, I have that memorized! And it's quickly becoming common usage in my circle of friends and acquaintances.
E.g., I read an interview of Sarah Polley (actress: Road to Avonlea, Beowulf and Grendel) who paused to sip her coffee and said, "Yuck! That tastes like santorum!"

Dan Savage, sex advice columnist, held a contest about 2 years ago asking for people to make up definitions for "santorum" (note lower case, therefore an entirely different word). Of all the submissions, he selected a half dozen or so and people voted on the most appropriate. This definition won hands down. Why? Ricky's obsession with the mechanics of how gay men make love, his attention to the nitty gritty (so to speak) details -- it is only right that this be acknowledged and commemorated.
