Anyway while breaking icy puddles last weekend (and imitating the sound they make) I learned a new expression: faire crac-crac (slang/sweet way to say 'make love').
Today while watching tv there was an ad that said:
"Oh, I guess he didn't faire crac-crac this morning!!"
Refering to the crunchy-toast biscuits on the left.
I just about peed my pants I was laughing so hard. And of course well pleased that learning this new expression proved useful ;-)
