SBNN = Song Before Night Night
Must admit this is the only BMW I have ever owned. As in (B)ob (M)arley & the (W)ailers.
When I lived on the UYupper West Side (are there still Yuppies?) in a different era, my neighbors said their BMW was an acronym for (B)reak (M)y (W)indow.
Get Up, Stand Up, folks.
