NERPS, or New Exciting Retail ProductS, are everywhere. They are great for breakfast, can cure your cough, are good luck, can whiten your teeth, can remove stains, will improve your gas mileage, and are always good for what ails you!
Adverts for NERPS are generally vague, ambiguous, and contradictory as to their exact nature or purpose. They are stand-ins for the latest trendy consumer product to hit the market, only to fade and be rapidly replaced.
Real life examples include: tamagotchi, pogs, pet rock, cell phone face plates, and kale chips.
