Dance with two tins (6)
I believe the answer is:
cancan
'dance' is the definition.
(I know that cancan is a type of choreography)
'with two tins' is the wordplay.
'two tins' means two substitutions for 'tin'.
'with' is a charade indicator (letters next to each other).
'tin' becomes 'can' (synonyms).
'tin' becomes 'can' (synonyms).
'can'+'can' is 'CANCAN'.
(Other definitions for cancan that I've seen before include "French female chorus line dance" , "Lively Parisian dance" , "Lively French dance, doubly permissive" , "Kicking entertainment" , "High-kicking French dance, once considered naughty" .)
