The act of moistening the anus with one's saliva before having anal-sex/foreplay
1) I gave her/him the Rusty Spittoon, which really seemed to make things slide in easier.
2) Without the Rusty Spittoon, I would have felt like my dick stepped into the Majave Desert.
3) Who needs to do use the Rusty Spittoon when you have lube?
