But I have an intuitive sense of how to use the word even if there's no settled definition. Eurotacky covers are brash even if not fast, and most dance that revs up fast is a bit funny in being fast, like chipmunks or silent movie comedies played on the wrong projector. And Scooter is faster than standard (and were faster in their earlier days, right) and do the cover tackiness and the silly sounds, and bassline gets to be honorary bosh in that the wibbly bass can add bosh that interrupts the melody, or the pop melodiousness adds bosh to what otherwise might be troppo serious sound weirdness.

Whereas the slow movement to Beethoven's Seventh is not bosh - unless someone does a bosh version.
