SlimePupgender is a sub-category of Pupgender and Slimegender, which falls under the Canisgender umbrella. Described as when the aspects of your gender feel very similar too, almost kin-like to the idea of puppies. The slime aspect comes into play as the different pup-like aspects of the [close to fragmented] gender can merge, or separate, like a slime, and form a new aspect of said person's gender, which may or may not use different pronouns. The slime aspect could probably be best described as when all of one's genders feel like differently gendered slimes mixing together, with different combinations and amounts coming to the surface at different times.
This could technically be considered akin to Genderfluid, as the aspects of one's gender can fluctuate depending on which portion of the slime is being prominent, hence the flux at the end of the title, since it fluctuates between the different states. This could also be considered a Neurogender, and is usually used by nuerodivergent people, and/or systems, as it fits the pup-like fluid aspects of their gender, but can also be used by nuerotypical people.
Flag History
The original flag, coined by Slime.Boi.Rawr on LGBTA Wiki, contains red, representing the hyper-activity that comes with the pup-like aspects of one's gender, next to orange, followed by a yellow line to signify the blending traits of slimegender and Pupgender. Then you have the white stripe, which stands for a lack of gender, as this term can be used for all terms. A neon green paw-print, green as the most common color for slime, and a paw for the pup-like aspects of the gender. Then you have the purple stripe, signifying a blurred line between male and female, blue and pink, as those are the traditional colors representing male and female. It was adapted by the0ender0system0 on LGBTA Wiki to be a bit simpler, but still holds the same meanings.
