toilet greaser 

Hand-job given (or received) in a truck stop restroom with a random trucker you met on the CB radio while on the road.

Hey truckers...heading out eastbound on I-10 for next 3 days. Honk & flash high-beams if you're up for a toilet greaser. (Doug Stanhope)

Toilet Greaser 

A spontaneous "Handjob" service produced by one male to another usually on the mutual grounds that both parties are straight and in need of relief

Hillbilly Job: "Yeah man, I'm telling yah, back in my day we would just get a quick toilet greaser after lunch and call it a day"

Jax: "you right"
