A material possession that designates someone as particularly wealthy and sophisticated; also, the state of being particularly wealthy and sophisticated. Gelatin was discovered in Victorian times, but only the most wealthy Victorians could afford it. They were actually more interested in crafting it into elaborate molds than in eating it; the more elaborate the mold, the more sophisticated the Victorian. Example: Wow, Sarah, that outfit is really jello!
