Pangender, or omnigender, is a gender identity in which a person either identifies as a countless number of separate identities that they are fluid between over time, or that they identify as one all encompassing identity. The genders that a pangender person has only includes genders within the person's own culture and life experience (e.g. their genders would not include Fa'afafine unless they are Samoan; their genders would not include bordergender unless they have Borderline Personality Disorder).
A pangender person's identity may or may not include genders not currently recognized or known and may or may not fluctuate in intensity or include differing intensities among the genders that the Pangender person encompasses. Thus a pangender person can also be genderfluid or genderflux. The combination of pangender and genderflux is called panflux.
Just like any other gender identity, pangender people can use any set of pronouns they choose or vary between pronouns depending on how they identify at the time.
An alternative term with a similar meaning is maxigender, since some people on Tumblr who don't identify as pangender argue that it is appropriative of culturally-specific and neurotype-specific genders. The reason for that, according to them, is that no one can identify as all genders, as this would include culturally-specific or neurotype-specific genders
Omnigender is sometimes used as a synonym for pangender, but sometimes is defined as experiencing almost all genders. Omnigender is also sometimes used to mean "gender neutral"/"treating all genders equally". Continue reading from Nonbinary Wiki
