Female is drunk, engaging another female in tussle (9)

I believe the answer is:

fistfight

'tussle' is the definition.

'female is drunk engaging another female' is the wordplay.
I cannot quite understand how this works, but
'female' could be 'f' (common abbreviation) and 'f' is present in the answer.
'is' is present in the answer.
This may be the basis of clue (or it may be nonsense).

'in' is the link.

I've seen this clue in The Times.
