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

'random woman' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'asks for mop fluid' is the wordplay.
'fluid' indicates anagramming the letters.
'asks'+'for'+'mop'='asksformop'
'asksformop' anagrammed gives 'MRS KAFOOPS'.
