cherchez la femme

I'm a little stuck... Click here to teach me more about this clue!

'she'll be the cause of the problem' is the definition.
I can't tell whether this definition defines the answer.

'czech female and her male crush' is the wordplay.
'and' is a charade indicator (letters next to each other).
'male' becomes 'm' (common abbreviation).
'crush' indicates anagramming the letters (I've seen 'crushed' mean this).
'czech'+'female'+'her'+'m'='czechfemaleherm'
'czechfemaleherm' with letters rearranged gives 'CHERCHEZ LA FEMME'.

Can you help me to learn more?
