Luksusfellen is a Norwegian reality television series in which financial experts help people who have lost control of their spending, so sløseri fits naturally as a shorthand for the habits the show confronts. The word itself simply means wastefulness or squandering in Norwegian, and in short online clips it has travelled beyond the programme as a compact reaction to extravagant purchases, unpaid bills and lifestyle spending. Its continued use comes from that directness: viewers do not need the full episode to understand the joke.
