Term first used in the Bob Dylan Song "I shall be Free" pronounced Un-yun Guhk
used to describe female undergarmets.
Well, I took me a woman late last night
I's three-fourths drunk she looked all right
'Til she started peelin' off her onion gook
She took off her wig, said, "How do I look" ?
I's high flyin', bare naked ...Out the window.
