Gallic shrugs

Useful, I've decided, for padding out a response when you basically haven't a clue whether they just complimented your attempted witticism or warned you that a pair of copulating toads were about to ruin the shine on your shoes.

'Crapeau' I later discovered did indeed mean toad and so where I should have shrugged, instead what I did next was probably completely inappropriate. Though, judging by their increased laughter the words I actually used and the actions to which I set them probably unwittingly expanded on their main focus of attention.
