Genres that share superficial conventions with other genres but have been taken out of their original context, resulting in obscured audiences and purposes. "[M]utt genres . . . mimic genres that mediate activities in other activity systems, but within the FYC [first-year composition] system their purposes and audiences are vague or even contradictory. They are quite different from and serve very different purposes in FYC than they do in other disciplinary activity systems" (Wardle, 2009, p. 774).
