Bring sandwich to the beat

Phrase used in northern England by grime and trap artists/fans, meaning 'to spit tight bars over a backing track in a punchy way'. The phrase evolved because 'sandwiched' is a synonym for the word 'tight', which is used as a compliment in grime and rap circles when appraising a song or performance. Can also start with variant words 'bringing' and 'brings' depending on usage and context.

That MC is spitting pure fire up there bruv. Sure can bring sandwich to the beat.
