In essence a milurge is a 'funny-looker' and as the word would imply it is someone that looks rather odd.
Usually specific to the males (female milurge = minger), not neccessarily though!
Dude, you're a milurge.
"look at that guy with short arms and a hairy back...what a milurge!"
Quasimodo, Courtney Love, Donald Trump are all examples of milurges!!!
