That's roughly the noise I just made as I sprayed (thankfully a fairly small amount of) water all over my desk and keyboard.
I just took the last cool, refreshing mouthfull of water from the glass on my desk. There was a chunk in it. After jetisoning the entire contents over said desk and keyboard, my worst fears were confirmed.
It was a bug. I HAD A BUG IN MY MOUTH!!
Call me a Drama Queen, but that's just not right.
