Well I've some funny Scottish words that the Scots probably don't know. Got some friends waaaaay up North who actually use these...

peedie = small
gaiy (sp?) = very (as in "It's gaiy cauld ben" = "It's very cold inside")
sharn = cowdung

Damn that's all I can think of for now. Scot's is great fun though.

American English wise, I hate the whole theatre/theater/cinema thing.
