When I was 5-7 I thought "let the bodies hit the floor" was "let the parties at the flow" I knew about that song because I watched youtube back then (this was like 2008-2010) so there was many videos with that song in the background. I didn't know much english but knew a few words. After I found out the name of the band was "drowning pool" I thought they lived in an inflatable empty swimming pool that was stranded at the middle of the ocean.
