Where does bet come from?

Bet originated in African American English slang in the 1980s. It was likely shortened from much older expressions such as you can bet on it or you bet, especially when these were used as exclamations meaning “of course” or “certainly.” Some of these, including you bet, are recorded in American English as far back as the 1850s, and are based on the verb bet, “to wager, stake, risk.” The current slang sense of bet gained prominence in the late 2010s and early 2020s as it spread on social media, and was employed with more playful or ironic uses. When used as a way to accept a challenge, bet may also allude to flippant expressions like “You wanna bet?”

How is bet used?

Use of bet is very context-dependent. As an affirmative, it is generally used as a single-word response to another statement. If one person says, “Let’s go out for tacos tonight,” another could reply, informally, “Bet. How about 7pm at our favorite spot?”

When meant ironically, it also used as a response, often as introduced by OK or similar words to emphasize its tone or intent, as in “You don’t think I can beat you in chess? OK, bet!” or “My company wants to give me a promotion without increasing my salary? Yeah, bet.”
