I've noticed in the last few months lots of my American friends saying it a lot (heaps!) in LJ or chat.
Did I just miss that this phrase is very common in the US? Is it a regional thing that hasn't hit Chicago yet? Am I just clueless to its ubiquity unless I hear it with an accent?
Or are you all just having me on because I'm in Australia and it's fun to throw Australian slang at me to point that out? If so, good on ya mate!
Ta for letting me know.
