Bosgender is a neurogender defined as "gender that has affinity with cattle, specifically the Texas Longhorn". It is a masculine aligned gender identity, and the flag conveys that with the horns and nostril ring. This is a flag for a gender that a headmate in the system experiences, who identifies with the stoic, solitary, dry, harsh lifestyle these beautiful cattle endure.
Bosgender was coined on August 15, 2018 by tumblr user packoflions via Beyond-MOGAI-Pride-Flags. The flag was created at the same time.
