I know there are sites out there designed for finding Lemmy communities that aren’t within your instance but it can be a difficult to find some more abstract ideas.

For example a community for goofy joke “million dollar” ideas like a gag gift for suburban moms that consists of divorce papers in a red frame that says “Break in case of emergency” or a gun that plays the Danny Phantom lines “He’s a phantom” or “I’m going ghost” whenever you pull the trigger.
