Bust / Bustin’
verb
Perform Well;
To perform strongly, go hard, or deliver with high energy — whether in a set, clash, freestyle, or general behaviour (“man’s bustin’ on the mic”). It signals intensity, hype, or skill in the moment. A separate, less grime-centric sense refers to sexual climax (“bust a nut”), borrowed from US rap and dancehall, but this is not the primary UK road usage.
