Often in the context of serious car audio installations that are capable of reproducing low frequency (often 15-40hz) loud enough to shake, vibrate the listener and car to the extent it gives the feeling of a massage.
In sentence:
"I was out late night driving, getting my bassage."
"Music was so loud it bassaged me."
"That's one helluva bassage!"
Beauty by usage.
Beausage sounds French but it's not; instead it's a synthetic combination of the words beauty and usage, and describes the beauty that comes with using something.
Beausage is:
* Roman amphitheater steps whose faces are worn away by the tread of thousands and thousands of shoes
* Stone chips on the hood of a Ferrari 250 which has been run hard and put away wet * A bike seat whose adapted form reflects that of its owner's posterior
* The look and feel of the cockpit of the old Mercedes pictured above (a jumble of replacement gauges and parts, obviously used a lot) -- that's 91 years of beausage!
