"Interrobang" is a "?" and "!" combined

The interrobang, also known as the interabang, ‽ (often represented by ?! or !?), is a nonstandard punctuation mark used in various written languages and intended to combine the functions of the question mark (also called the "interrogative point") and the exclamation mark or exclamation point (known in printers' and programmers' jargon as the "bang"). The glyph is a superimposition of these two marks.

Many writers, especially in informal writing, have used multiple punctuation marks to end a sentence expressing surprise and question. What the...?! Neves, Called Dead in Fall, Denies It (headline from San Francisco Examiner, May 9, 1936)
