n. Did you hear what Dick did? He friended everybody at work, then uploaded pictures from a porn site and tagged them all. What a Facebook Judas.
A British metal band who gained international notice in the late 70s and were one of the most popular names of the 80s. Largely responsible for the traditional heavy metal sound through their influential 70s work, and established the important genre of speed metal. Also notorious for featuring singer Rob Halford, who came out of the closet as gay after his departure from the band in 1993. (He rejoined the band in the summer of 2003.)
If you don't like Judas Priest, then you simply don't like metal.
(Catholicism) The act of leaving Mass early, typically between receiving communion and the concluding rite, without a justifiable reason for doing so. The Judas shuffle is named after Judas Iscariot, who left the Last Supper (the first Mass/Divine Liturgy) early in order to summon the guards to arrest Jesus.
My brother did the Judas shuffle because he wanted to watch the football game.
