Petallus, who am I to doubt your word. And yet - I just have to say I cannot believe that you've never ever 'broken wind' - come on, pull the other one
I'd only been in the UK a few weeks, when I was invited to a family for Sunday lunch (my future OH's family) - after lunch, he and his brother went to help mum in the kitchen, and just wouldn't let me give a hand. There I was, stuck in the lounge with future fil and he put telly on. Ski Sunday - and he commented 'can't see any difference between them, they all seem to ski the same, and with only minute differences in timing'. Trying to make polite conversation in my very rough English, I said 'well, the equipment makes a lot of difference too, and farting also'. He looked at me with a strange look on his face, so I thought I had to explain further 'yes I said, farting is an art in skiing - the better you fart the faster you go. They take the temperature of the snow at different parts of the piste, and measure the humidity and then fart accordingly. Same as choosing tyres for Formula One racing'. So he called the sons back 'I have a bit of a language problem with your little Swiss friend' he said. So the boys asked what I said and I repeated. They laughed so much - and then explained. I've never lived it down!!! Still a family joke 43 years later.
In French 'farter' means 'to apply wax [to sole of skis], and I thought it was the same in English! There was some logic in it though ...
