As a consequence of its performative turn, the critical literature on populism has dedicated increasing attention to its socio-cultural and stylistic features. Among the most prominent concepts underpinning this approach is the notion that populism relies on the "flaunting of the low" or the use of "bad manners". This article engages in an extensive discussion of the way this concept is used in the literature and showcases its main limitations. In replacement, I then suggest the alternative concept of transgression, understood as the violation of a norm, which has the substantial advantages of being more flexible and versatile, as well as less reliant on a normative binary. I then develop an associated typology of transgressive performances depending on which type of norms is being disrupted: transgressions of interactional norms, transgressions of rhetoric norms and transgressions of theatrical norms. This article then concludes on the potential of considering transgression beyond populism.
