The phrasal verb "sell out" is predominantly used in informal contexts, though it can appear in formal contexts, particularly in discussions about commerce or economics. It can have several meanings, all revolving around the concept of completely selling goods or products until none are left in stock, often used in retail and event promotions such as tickets being sold out quickly. In a more abstract, metaphorical sense, it also conveys the idea of compromising one's principles or values, typically for financial gain, which is a usage common in cultural or artistic discussions to critique individuals or organizations perceived to prioritize profits over authenticity. This dual usage makes "sell out" versatile, capable of describing both concrete scenarios in business and abstract situations regarding personal integrity.
