Hi, I'm Maki. Somehow I've gotten to the point that I've done enough stuff in this community that I need a website now to catalogue stuff.
Agecusp
A term for those whose age is on the cusp between two ages. As such, they don't fully identify with either age, but still feel connected to both in some way. This can be used for linear ages (ex. 17 & 18), non-linear ages (ex. 20 & 40), xenoages (ex. pinkage & purpleage), or any other age identities.
