Used for exclamatory purposes. Like when you are really excited. Can be shortened to just "kook". The Osound is held out longer the more important it is or the more surprised you are.
Him: So I got an F on my term paper Her: Kooooook!

n: A nerdy person prone to making lame jokes and giggling. The kookamonga will often accuse others of being a kookamonga, but like a hipster a true kookamonga will refute accusations of actually being one. In true hipster like fashion the kookamonga will disregard fashion rules, social norms, and rules of hygiene but not to be ironic, just because they are dorks who do not care (or in some cases do not know). They would be cute if they stopped calling other people kookamongas. The nerdy version of a hipster, kookamongas live their lives in denial of what they truly are.

Look at that guy strutting down the street giggling in his nerd shirt, what a kookamonga.
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
