[Recognized] shorthand on the Usenet group comp.std.c for any unexpected behavior of a C compiler on encountering an [undefined] construct. During a discussion on that group in early 1992, a regular remarked "When the compiler encounters a given undefined construct it is legal for it to make demons fly out of your nose" (the implication is that the compiler may choose any [arbitrarily] bizarre way to interpret the code without violating the ANSI C standard). Someone else followed up with a reference to "nasal demons", which quickly became established. (see Jargon)
