The interrobang (often represented by ?!, !?, ?!? or !?!) is an unconventional punctuation mark used in various written languages and intended to combine the functions of the question mark, or interrogative point; and the exclamation mark, or exclamation point, known in the jargon of printers and programmers as a "bang". The interrobang was first proposed in 1962 by Martin K. Speckter.
