Yippee-ki-yay

"Yippee-ki-yay" is an expression popularized by the film character John McClane from the "Die Hard" series. It is a playful, spirited phrase often used to convey confidence, excitement, or a rebellious attitude. The phrase combines "Yippee," indicating joy or enthusiasm, with "ki-yay," which adds a rugged, Western-inspired flair. Though not deeply meaningful, it has become a cultural catchphrase symbolizing defiance and bravado in challenging situations, often associated with action heroes and tough characters.
