bet

Bet means “okay,” “sure” or “deal.” It’s a quick, confident way to agree to a plan or accept what someone said.

What does bet mean?

As slang, “bet” is a one-word yes. If a friend says “meet at 7?”, replying “bet” means “sounds good, I’ll be there.” It can also mean “I believe you” or “challenge accepted,” depending on context.

Sometimes it’s used as a dare or a skeptical challenge: “Bet you can’t eat the whole thing.” And “say less, bet” stacks two agreements for extra enthusiasm.

How to use bet

• A: “Pick you up at 8?” B: “Bet.”
• A: “I’ll send you the notes tonight.” B: “Bet, thanks.”
• “Bet. See you there.”
• A: “I can beat you at this game.” B: “Bet.” (challenge accepted)

Bet vs. say less

Both mean “agreed.” Say less adds the sense that you don’t need any more convincing. Bet is shorter and works in almost any situation where you’d say “okay.”

Where bet comes from

The expression “You bet!” has been used as an enthusiastic yes since at least the 1850s, according to Dictionary.com, which says the short slang “bet” likely originated in Black slang and was recorded in a 1990s campus slang collection. It’s now one of the most widely used slang replies among young people.
