Definition & Meaning of "bust off"in English

What does "bust off" mean in African American slang?

It is used in African American Vernacular English (AAVE) and hip hop culture, particularly in gangsta rap and street slang, to describe starting to shoot a gun, often suddenly or aggressively, typically at a rival or enemy. People typically say "He bust off at the opps" or "They bust off as soon as they saw the police." The term originated in late 20th century urban AAVE, especially in East Coast and Southern hip hop scenes, and remains common in street narratives, drill music, and crime related slang.
