Is she confirming something? Or denying something?

'No it isn't!'
or:
'It is too!'


Or was the male study object not the last person to speak before her mysterious utterance? Is it a follow-up to something the female said herself? Is she re-affirming an earlier statement? Is she merely drawing attention, trying to get the male to rejoin the conversation?

It means "I find Frenchmen terrible attractive".
Hmmm...I'm not so sure. I've heard this exact same sentence in all kinds of English variants, but none resembled this one. Most utilised the Germanic capacity for brevity in full, by communicating this entire sentence with a series of single grunts, such as ''oh' followed by 'ah'.
