Why has "smooth as butter" become such an overly used phrase in the tech world? Listening to the last Apple product release I must have heard the word butter a few dozen times.

I don't know about anyone else but this phrase is really starting to annoy me. It's overly used, and the word "butter" in my mind is closer to "greasy", like "don't touch it with your finger because it'll get slimy and you'll have to wash your hands". Can't you just say "smooth" or "without any perceptible lag"?

EDIT: Seriously, this doesn't bug anyone else?
