Said when something is too awesome for all other words or word phrases. Can be used as an adjective, noun, or a verb. When you say it, you must exclaim it in a high pitched, enthusiastic voice. If you use it wrong, you're dumb.
The opposite is Oh Never! Which is used when you are describing or reacting to something that is terrible or something that you would never do.

1) A typical ending to a brainless teenage girls' photo album, such as "Summmer 0999" or " City with the bfffs 09". Because of this, it has now become a common phrase used to bash popular culture that constantly refers to the year 2009. It works best as a sassy ending to a statement, and should usually be used in tandem with a peace sign held uncomfortably close to the face.
