When a secret
plan or scheme to accomplish some purpose in a storyline of a TV show or movie is so absurd, preposterous, or silly that
it is unworthy of serious consideration.
Usually leads the viewer
into a fit of yelling at the movie/show, sometimes
throwing things in frustration.
"So the Joker
really arranged a big truck chase just so that he could get caught and go to prison, then
he could kidnap
a guard and grab his phone to make
the call to set off the bomb he'd previously sewn inside
the henchman in the next cell? That's ploticulous."
