spit jack

to give a male a handjob with spit as the lube.

My girlfriend gave me a spit jack at the movie theater last night.

spit-lube jack-off

A spit-lube jack-off is a masturbation session that a guy gives himself using his own saliva for lube if he's circumcised and out of his favorite lubricant.

Since I'm cut high & tight, when I'm out of Sliquid, I just have a spit-lube jack-off!
