Interrobang

The interrobang (/ɪnˈtɛrəbæŋ/), also known as the interabang ‽ (sometimes rendered as ?!, !?, ?!?, ?!!, !??, or !?!), is an unconventional punctuation mark intended to combine the functions of the question mark (also known as the interrogative point) and the exclamation mark (also known in the jargon of printers and programmers as a "bang"). The glyph is a ligature of these two marks and was first proposed in 1962 by Martin K. Speckter.
