Euphemism for the constant buzzing and hissing heard on vinyl records.
Used by fans of vinyl, who claim this distortion makes records sound better than CDs; which sound too "clean".
Vinyl Fan: Here let me put on this record, then you'll understand. (Record starts playing) Do you hear the warmth?
Normal Guy: Warmth? I just hear a bunch of hissing under the music. Why is that better than a CD?
