‘扔钱’ literally means 'to throw money' — a vivid, figurative expression describing reckless, wasteful, or impulsive spending. The verb 扔 (rēng) conveys forceful, careless disposal, while 钱 (qián) is 'money'; together, they evoke the image of tossing cash away like trash, emphasizing lack of thought or value judgment. This phrase is informal and often carries strong disapproval or teasing tone.

It’s commonly used in spoken Chinese to criticize extravagant purchases (e.g., luxury items bought on whim), overspending on low-value services, or funding unrealistic ventures without due diligence. Though not strictly slang, it appears frequently in casual conversation, social media commentary, and family banter — especially when someone spends far beyond practical need or budget. It implies moral or financial irresponsibility rather than mere generosity.
