A phrase of monumentous proportions created through exclamation mark mayhem which may be used in a number of grammatical constructions.
(ex 1) It must be featured at the end of a sentence, usually following at least one exclamation mark, or replacing such markings entirely.
(ex 2) It may stand alone as a beginning and end of sentence (or phrase) in and of itself, however the grammatical stipulation is that it must be utterly spontaneous barring that it is a response in a conversation. For example, in such a situation as the middle of class.
It is most commonly found in light-hearted conversations, but may be used during a serious discussion (creators will not be held responsible for adverse results of such useofnero).
It is pronounced quickly, as an attachment to the previous word if such exists.
