Interrobang
The interrobang or interabang[1] (pronounced /ɪnˈtɛrəbæŋ/), ‽, is a nonstandard English-language punctuation mark intended to combine the functions of the question mark (also called the interrogative point) and the exclamation mark or exclamation point (known in printers’ jargon as the bang). The ligature is a superimposition of those two marks.
