Spiteful woman welcoming strip show (7)
I believe the answer is:
cabaret
'show' is the definition.
(I've seen this before)
'spiteful woman welcoming strip' is the wordplay.
'spiteful woman' becomes 'cat'.
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'strip' becomes 'bare' ('bare' can be a synonym of 'strip').
'cat' placed around 'bare' is 'CABARET'.
(Other definitions for cabaret that I've seen before include "Film set in 1931 Berlin - floor show" , "Revue" , "Series of acts" , "Entertainment at night club" , "Bear cat (anag.)" .)
