spit on your ass

Duckie, Decay- and I were at The FUNhouse one evening talking about past sexual exploits. As it turned out, Decay- and Duckie had had a few people in common. Decay- was relating how once when he was having impromptu sex with someone and there was no lube convenient, "...well he just spit on my ass and went with that..." This absolutely horrified Duckie, who felt that nothing would make him wilt faster than hearing somebody clear his throat and *haaaaaaaaaak-p'tooo* on his butthole. The phrase "spit on your ass" has since become a sure way to gross out Duckie.
