Kindergender: A gender that feels very childish, hyperactive, and/or impulsive. Note: 4hcan has pretty much ruined this term since they made another, not so great, definition for it. This definition's older but it would be good to use an alternate term if you don't want to be associated with the troll meaning. Alternative suggestion: impulgender (suggested by lesbiancrocker)

Kinegender or Kinetigender: A gender experience that constantly moves or is in motion, similar to genderfluid or genderflux.

Kitharagender: A gender which is similar to guitar strings (strings being for acoustic, electric, or nylon vary upon the person) and therefore enjoys having them ‘strummed’ by immemorgender people. 

Kronosgender or Chronosgender: When you're different genders at different times of the day. Derived from "Chronos" the Greek god of time. Note: Kronos (or Cronus) and Chronos are often confused because of how similar they are, but they are different deities. The coiner mistakenly named it Kronosgender. Not to be confused with Chronogender.
