A person who turns up their music so loud you can hear the
bass outside of the area it is being played, especially in your own apartment/
house/car.
"
Man, I got no sleep last
night."
"Why?"
"The basstard who lives above me was at it all night with that obnoxious techno music."
"The basstard's still alive?"
"Yeah."
"Then whose
coffee did I poison...?"
