Busk it is a British informal phrase meaning to improvise or wing it — to proceed without preparation, relying on ability, bluff, and confidence rather than prior planning. It carries a slightly plucky, make-do spirit: you don't know exactly what you're doing, but you'll figure it out as you go. Common in British work and social contexts when plans fall through and someone has to perform or manage without the usual support. The register is casual and pragmatic.
