An ingratiating and thus now outmoded style of singing popularised in the early 1990s by Pearl Jam's Eddie Vedder.
Apparently still in use by Christian Rock vocalists and soon-to-be bargain-bin emo-punk groups.
Pronounced Grr-air or like Greg but with 'air' instead of 'g' at the end.
Why do all of these fucking holy rollers sing Greh? It hasn't been popular for over a decade!
An interjection showing discontent, see a slightly more exaggerated version of "feh".
Greh, this completely sucks.
