Skiddelyding
First you must know the definition of Onomatopoeia..the representation of a sound by an imitation thereof..like the cat mews. Think of noises in a comic book. Bang!

Skiddelyding should be used anytime something good happens to you. Skiddelyding originates from the noise made in Super Mario Bros. when Mario collects a coin. Most recently used everytime my fantasy football app updates and my team scores more points. hence, Skiddelyding. Use it!
Skiddelyding!

I just won the lottery! Skiddelyding!
