Back massage on street leads to rupture (5)
I believe the answer is:
burst
'rupture' is the definition.
(I've seen this before)
'back massage on street' is the wordplay.
'back' says the letters should be written backwards.
'massage' becomes 'rub' (rub can mean to massage).
'on' is a charade indicator (letters next to each other).
'street' becomes 'st' (abbreviation).
'rub' written backwards gives 'bur'.
'bur'+'st'='BURST'
'leads to' is the link.
(Other definitions for burst that I've seen before include "Pop" , "Fit" , "Exploded" , "Blow up" , "Rupture" .)
