A combination of your eye balls and your ears. To be used when both senses are used simultaneously for the same purpose, like watching and listening to a concert.
Oh my god! That concert was terrible! It made my ear-balls bleed!
When you have to wake up early as feck. When you beat the sun, and get out of bed at the ass-crack of dawn crying "bring it on!". It's a gung-ho jolly sort of good time
We ask that you please pardon Mr. Carrell's not-so-sunny disposition...he was up balls early today.
