nigger alarm 

The bass vibrations of a nigger song from an ostentatious car stereo system. The rest of the song cannot be heard, but the bass alerts nearby white people, whether in their cars or at home, that a nigger is in the vicinity.

Also works for wiggers.

"Honey, why are the windows shaking?"
"Uh oh, it's a nigger alarm, better load the shotgun."
