Cassboy (also known as cassman or cassmale) is an identity that can be used by any individual regardless of if they are cisn't, transgender, non-binary or cis. It is an identity where one feels that their gender is unimportant but still is a boy/male. A cassboy has a gender, that gender being male, but feels it's not an important part of their identity.
The female-aligned counterpart is cassgirl (also known as casswoman or cassfemale) where one feels that their gender is unimportant but still is a girl/female.
The neutral equivalent is cassenby (also known as cassnonbinary) where one feels that their gender is unimportant but still is non-binary.
Cassboy, cassgirl, and cassenby are all subsets of cassgender.
