So the next time you decide to go to the big sale at the mall, you can thoroughly impress your fellow humans by the usage of such a word in your sentence. "Bye honey!

I'm sure i'll have lots of fun explaining this to the mechanic on thursday. Arrghhh.. the trails of having such expert hearing... good for eavesdropping on parental conversations when you are 12 through the heating vents, not so useful when you are attempting to drive in peace and are constantly reminded by an annoying little squeak just under my seat.
