1) (Expression) (Informal): A bursting feeling of extreme joy or exultation beyond any other conceivable form of expression. Usually voiced in a
high pitched, uniquely
individual sound, sometimes not even similar to the original word - it really depends on how excited the
individual is.
2) (Noun) (Informal): To describe one's elation about a particular thing or situation. Pronounced in the same way as above.
Origin: First derived from High-School geometry assignments where angles of a shape needed to be solved. The angles that were already solved for you were labeled as "Given".
