bassage

Means being "massaged" by loud bass music.

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!"
