This is no more than a vague idea i have...something like posting a good idea, followed by a slight tweak to that which makes it a far worse idea. Maybe by changing a word or the word sequence. I think I got this notion from remembering an 80s/90s animated show so it might be a complete car crash!
Example:
Good idea: Eating white snow in the inter when you have no water
Bad idea: eating yellow snow
