Yippee ki-yay

[Tina]

This is the correct spelling, dont let anyone tell you otherwise. Commonly proceeded by the words [mother] and [fucker] and particularly used towards terrorists.

Basically, Yippee ki-yay is an old, American cowboy expression, like: ”yippee”, or “yeehaw (heehaw)”, or “Whoopee”; expressions of extreme joy or excitement, commonly associated with cowboys. As an interjection, “yahoo”, plays a similar role.
PS.: Many people mention the expression “Yippee ki-yay” in the movie “Die Hard” as the origin of the work, but it is important to know that this word is much order. Like I said: from the “cowboys-days”.
