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...?"
