What is the origin and context of use of 'based'?

The use of "based" as an interjection has evolved from its original context in African American Vernacular English (AAVE) and internet culture. Originally, "based" was used to describe someone or something that was considered authentic, genuine, or true to oneself. Over time, "based" transitioned from its specific meaning to a broader internet slang term used to express approval, agreement, or admiration for someone's actions, statements, or beliefs.
