oops, i forgot mine... I like and grew up with "Uffda" (pronounced Oof-dah) norweigian, it is multi-purposed and can be used as "oh my goodness" or "wow" i.e. "Uffda! my back hurts!" "Uffda! You worked hard today!"

and this one had me laughing very hard! "Biggie - This is unusual. A biggie is what a child calls his poo! Hence the reason Wendy's Hamburgers has never really taken off in England - who would buy "biggie fries"? Yuck - I'm sure you wouldn't buy poo fries! The other meaning of Biggie is erection. It just gets worse!"
