Cassromantic is an identity where one feels that one is indifferent to the idea of romanticism, and believes it is not an important part of their identity. A cassromantic individual may be on the aromantic spectrum, but not all cassromantic indivduals identify with the aromantic spectrum.
It is similar to, but is not the same as pomoromantic, in which one denies labels for their romantic orientation. Cassromantic people can have a romantic orientation, but they do not care about it, whether if they are alloromantic or aromantic.
The sexual counterpart is cassexual.
