I've heard the expression being used in Die Hard, although I understand the overall sentiment, I still want to know what "Yippee Kayay" means exactly and where it comes from? Thanks in Advance!
"Yippie-aye-ay" was a joyful shout, especially associated with cowboys and cowboy-type songs...Frankie Laine comes to mind, for example. The basic word, 'yippee', was just a shout of joy or excitement as in "Yippee! We're off to the circus today!"
