so i speak french, english and spanish
i have a little knowledge in romanian and tahitian
and i also speak my island dialect so "créole" i have no idea if that might ring a bell for a non french speaker! (btw there are several different créole, mine is from Reunion island! there is also Caribbean creole for ex)

i'd rather just speak English to be honest but i have to admit that insults sound better in French (and in creole for what it is worth)
