this name is a morph between the legendary singer of Panic! At The Disco Brendon Urie and legend Elvis Presley. A fan has started to call him this way after he beautifully sang "Can't help falling in love" on one of his twitch live streams and this name's ever since spreaded like wildfire.
"Yo man Belvis Purie has such a nice voice! He should sing at our wedding"
-"Yes we only approve Belvis Purie"
