Marc Polet and his wife were out on their farm in Belgium when a wild boar approached at breakneck speed and attacked! But then their miniature ponies spring into action and chase the boar off. That’s a good pony. Those who speak French say the commentary is quite amusing, but outside of a couple of familiar epithets, I can’t understand a word. Therefore, this may contain NSFW language in French. -via Viral Viral Videos
it means "whore", but could be best translated by "oh shit"! Not very polite, but common; excuse their French!
it seems that they saw the boar before and were lookin for it, hence the videotaping.
At the end the lady feeled scared with trembling legs, and the guy said that the horses protected them ;)
