And an interrobang is this awesome little piece of punctuation '‽' Here's hoping that it will appear. In the words of Wikipedia an Interrobang can be described as: A sentence ending with an interrobang asks a question in an excited manner, expresses excitement or disbelief in the form of a question, or asks a rhetorical question. For example: Say what‽ She's pregnant‽ In informal English, the same inflection is usually notated by ending a sentence with first a question mark and then an exclamation mark, or vice versa.
