When someone does something
stupid by themself.
They either choose to, are force to, or symply end up proceeding alone on a mission that shows very
little likleyhood of a
non-negative outcome.
"I'm not riding along for this death-defying
stunt! Better make it a Solo-Act, man!"
"Johnny went on some kind of Solo-Act last night and ended up in jail."
"Fuck it! If nobody wants to roll with me, I'll do a Solo-Act! Then I
don't have to split the
money!"
