This article examines how internet memes, a distinctive type of user-generated content, have served as a vehicle for the co-destruction of the Airbnb brand. For this purpose, we discuss the relevance of internet memes alongside the doppelgänger brand image concept, which explains the logic behind disparaging brand imagery that circulates within internet culture. A comprehensive research model is developed that links several meme- and user-related characteristics with both meme virality and the brand image of Airbnb. The proposed multilevel model is tested using a split-sample approach on a dataset that includes 121 Airbnb-related memes evaluated by 3,664 participants. The results reveal that the virality of disparaging memes is mainly driven by humor, unambiguity, pictorial format, inoffensive content, and “active” user status. The perceived brand image is, however, mainly affected by the valence (negativity) of the memes, while the meme content and user status are also important.
