A cry for help!

Hey, majority of watchers!

You're American, right? /obvious

I'm doing a project at college (what, Pidge, are you actually working? Yes, yes I am) about the differences between British English and American English. I need some stereotypically American phrases and amusing miscommunications. (Unfortunately I can't use the usual "rubber vs rubber" that first came to mind.) Any random help would be appreciated.

Additionally, anyone Australian, similar to the above request?

/wishes she was at home instead of in this stupid class

Edit: I'm not allowed to include anything naughty in my essay guys, the examiners are stuck up. :| So stuff like the difference between "wank" in American and "wank" in British are not applicable. <3 You keep using that word. I don't think it means what you think it means.
