LOL, yeah. I used to game with a group of Aussies and I was always having to ask them, "What does that mean?!" or "WTH are you guys talking about?!" lol. Took a few but I learned a fair amount of Aussie slang that way though.that’s a comfort :0)
Early on in my career I worked with a client in the US and as I got to know them more I found my self lapsing into using slang words and quickly realised that there were words used in the UK that didn’t transfer well to my US counterparts, nothing embarrassing or rude most simply led to mild confusion.
