Every once in a while I like to bust out the word "balderdash", I use it in place of 'nonsense'.
So if someone says, 'the Oilers are a good hockey team', instead of saying Nonsense!, you just shout out Balderdash!, they are a terrible hockey team!. I just find it's a fun adjective to throw in because it throws most people off when you say it.
