Like a skit thus involving girl from the south (7)
I believe the answer is:
satiric
'like a skit' is the definition.
(a skit might be satirical)
'thus involving girl from the south' is the wordplay.
'thus' becomes 'sic' ('thus' in Latin).
'involving' means one lot of letters goes inside another.
'girl' becomes 'rita' (woman's name).
'from the south' is a reversal indicator (in a down clue, letters go up).
'rita' written backwards gives 'atir'.
'sic' going around 'atir' is 'SATIRIC'.
(Other definitions for satiric that I've seen before include "Using ridicule" , "Relating to sarcastic writing" , "Disparaging" , "Using mockery" , "with comedic content" .)
