Absorgender is a gender in which one absorbs the genders of the people around them. As one is around more people more genders are added to the genders one feels, even after the people leave one still feels their gender. These genders remain until one hits a 'max', at which point they become a blank slate, and revert to a single 'base gender'. This base gender can be any gender, including agender. For some people this 'base gender' may be different each time.
If one absorbs a particular gender more easily than other genders, one can use absor- as a modifier for that gender. For example, absorgirl, absornonbinary, absorboy, etc.
Flag
The original flag was first proposed by tumblr user @nepkrisprite as late as July 9, 2016. The colors overlapping and mixing refers to absorgenders taking in the genders around them. The black in the center references how the color black absorbs all colors of light to produce the color black.
The alternate flag was proposed by wiki user Someconfusedfurry on Spetember 22, 2020. Blue represents masculinity, pink represents femininity, yellow, green, and purple represent gender neutral/non binary/xenic identities. Gray represents genderlessness. The overlapping circles represent how an absorgender person "absorbs" genders around them.
Another alternative flag was designed by an anonymous wiki user on October 15, 2020. Yellow represents abinary genders. Blue represents man/man-aligned/masculine genders. Pink represents woman/woman-aligned/feminine genders. The colors in between (green, purple, orange) represent blends/combinations of these genders, as well as having multiple genders as a result of collecting/absorbing them.
