If you break it down, you get "bio" and "solids." Solids are good, right? Wouldn't want to be floating around the universe on a ball of water. "Bio" is good too, it suggests something wholesome and natural, like "biodegradeable" and "biofuels."
Maybe "biosolids" are the new snack of the future we'll all be eating!"Mom, can I have some change for the biosolids dispenser?"
What it Actually Refers to...
Something that is neither wholesome nor solid: sewage sludge. More commonly known as "shit-festooned muck."
The bigger question here is: Why? We understand why scientists invent a term like "binocular deprivation;" they want to maintain a certain image for a sometimes sensitive public. But who's out there trying to improve the image of shit?
