Meta-cold dark matter
Meta-cold dark matter, also known as mCDM, is a form of cold dark matter proposed to solve the cuspy halo problem. It consists of particles "that emerge relatively late in cosmic time (z ≲ 1000) and are born non-relativistic from the decays of cold particles".[1]

gollark: I guess neutral is kind of more "mean" than "median", at least.
gollark: In that case people would have to fall into either "very good" or "very evil" most of the time.
