(pronounced "jahss") (noun) Jack Off Session. Occurs among two or more males at sleep overs, camp outs, etc., when group sex talk, watching sexy movies, or homoerotic wrestling matches makes one guy horny, and he has to leave the group to find a private place for some quality masturbation. Internet access is usually preferred, but not necessary. If multiple males leave together for a jos, the jos is called a circle jerk.
I got so fuckin' horny talkin' with my buddies about the camp counselor's tits that I had to go to the showers to have a jos.
