Flopgender is a faunagender defined as "a gender that is small, fluffy, cute or soft and/or any other quality associated with Leporidae babies, that is Leporidae-like and/or connected to Leporidae babies". It was made with neurodivergent people and age regressors in mind, but can be used by anyone and is therefore not strictly a neurogender.
Leboridae like animals include bunnies, rabbits, hares and leverets. Someone can be connected to any of these Leboridae animals as long as they are babies such as being connected to rabbit babies (bunnies) and hare babies (leverets).
Similar identities include Bunnygender
