“Welcome to Fandango’s One-Word Challenge (aka, FOWC). It’s designed to fill the void after WordPress bailed on its daily one-word prompt. Today’s word is “Bugaboo.””  (https://fivedotoh.com/2019/10/11/fowc-with-fandango-bugaboo/)

What a weird word!  It means so many things:  1 : an imaginary object of fear. 2 : bugbear sense 2 also : something that causes fear or distress out of proportion to its importance.  Slang: Someone who is clingy and blows up your cellphone.

How about this bugaboo taking over the world?
