Claremont hole
A hole in a story into which sub-plots fall, forgotten forever. Taken from Chris Claremont, former writer of the X-Men, who left dozens, if not hundreds, of stories unfinished.
"How come in the TV show 'Birds of Prey', all the main characters are said to have jobs, but they never go to them and they never seem to be fired from them either?"
"Ah, their jobs fell down a Claremont hole."
