“Stunting” generally refers to a false claim or staged issue to achieve some goal. Sometimes a person may talk about themselves or others “stunting off a unit.” This could include a range of actions from making a false claim of endangerment to a claim that consensual sex was rape to paying someone to assault the person stunting. Some people may also call self-harm to get a move to an isolation cell or transfer to a mental health unit stunting, but that seems to be a less common usage.
