Vocigender is a xenogender which is weak and hollow feeling, rather than a specific, certain gender. For example, a vocigirl would feel somewhat female, but not completely, since the sense of being female is not strong. It is similar to greygender, but vocigender can be used as prefix to make genders like vocigirl, vociboy, and vocifluid. It is based off the Latin vocivus meaning empty or void.
Vocigender was coined by Tumblr user Yuukikaai on July 7, 2014. The flag was created by the user pridearchive on July 14, 2014. The color meanings are as follows: Black represents agender, genderlessness. The color can be changed based on one's specific gender (for example, vocigirl would be red). In this case green represents non-binary gender, as well as agender. White represents an amalgamation of all genders. The circle also represents the hollowness of vocigender.
