The colloquial term for a rotating tray often placed on a table to aid in distributing food is a "lazy Susan." A lazy Susan typically consists of a circular tray or turntable that can be spun or rotated, allowing easy access to items placed on it. It is commonly used in dining settings, especially during family meals or gatherings, where multiple dishes or condiments are placed on the tray for easy sharing and serving. By spinning the lazy Susan, individuals can reach different items without needing to pass them around the table. The term "lazy Susan" is believed to have originated in the early 20th century, and its exact etymology is unclear.
