A slang term for product that is relatively useless and/or easily replaceable and rediculously overpriced
I once bought a metal bar for $129.99 to do situps. Than I realized I could just use a sofa or purchase a similar product for $19.99. What a solid-situp

Person 1: Hey, I just bought a snuggie!
Person 2: Wow, that sounds like a solid-situp to me. Why wouldnt you just cut two holes in a blanket?
