The dialect article on the main page is highly entertaining. I really like discovering how different groups pronounce/call things. So what is your favourite dialect pronunciation or slang?
I'm torn between turlet/toilet and hoo-er/whore. I'm not even sure of which accent/dialect uses those, unless "bearded old man from the Simpsons" is a recognized American Dialect.
And let's not get into pop/soda/coke/fizzy drinks or sandwich/hoagie/sub/po'boy. We all know how those devolve into murder.
