App-mediated ride sharing services like Uber and Lyft represent a relatively new chronotope that shapes
participants’ identities and relationships through specific space and time configurations. Ridesharing services such as these blur
the boundaries between what is public/private, familiar/unfamiliar, and interactional/transactional, resulting in chronotopically
specific scenarios that are often humorously exploited by stand-up comedians in their routines. In this paper, we analyze several
short video clips of performances posted by comedians on TikTok comprising narratives about Uber/Lyft experiences from the
perspective of the ridesharing passenger. Our findings show that in these comedic performances the ridesharing chronotope is
characterized by various forms of relational ambiguity and that this relational ambiguity structures interactional frames for its
participants. Through their comedic artistry, comedians animate the diverse voices engaged in these types of encounters, shedding
light on variable norms and ideologies underlying ridesharing interactions. This study addresses a novel context and an as-yet
unexplored topic: the language used by stand-up comedians who make their performances available to audiences through their social
media accounts. Methodologically, the affordances of TikTok facilitate the identification of topically similar comedic content,
resulting in a topic-based, rather than a performer-driven, analysis.
