(pronounced
like "loss") vb. Also: WoSsing, WoSsed.
To mix the
music in a concert so badly as to crate a Wall of
Sound. Occurs most often in Metal shows, but can happen anywhere there's a terrible mixer.
Dude, I was so psyched for the Mars Volta show, but then the
mixer totally WoSsed it. That ruined my
night.
