This Guy Totally Lit a Candle For Nate McLouth

After chiding the Pittsburgh Pirates ownership for trading Nate McLouth through song, this troubadour segued into a special Nate McLouth cover version of "Candle in the Wind": "Goodbye, Nate McLouth, though I never knew you at all, you had the gold glove undeserved, but you sure could smack that ball..." Seriously though, is 'jagoff' a regional colloquialism specific to Western Pennsylvania? (via Dejan Kovacevic's morning links which are just like Jimmy Dean's morning links except with less sodium)
