A solo
A porn movie where someone just wanks alone. Like they have no life and nothing better to do.
"That movie is just a guy wanking by himself. That’s a solo.", @PornJunkie
"A solo is when you’re the only one in the movie and you just wank the whole time.", @MovieAnalyst
"That’s a solo. One person, one wank. That’s it.", @WankingLife"
