Dollgender is a kingender that was originally coined by a troll in a deleted post that was defined as "a gender that closely resembles agender, but is strongly influenced by one's identification as or with dolls. can also be used as dollgirl, dollboy, dollenby, etc. Most commonly associated with dollkin, but one is not required to be dollkin to identify as dollgender."
The term was coined again by a different individual who was not a troll to mean "A gender that is fragile with soft feminine and neutral energy or a gender relating to a doll-related kintype."
History
Dollgender was first coined before June 18, 2018 by a Tumblr troll. The non-troll version of the term was coined on December 3, 2018[1]. The non-troll flag was created at the same time as the non-troll term. The meanings of the first two flags are unknown.
