Abroachillean is a more specific version of abrosexual/abroromantic. Its when one who is a male/male-aligned gender (i.e. demiboy, genderfaun, boyflux, etc.) is abrosexual, but is only fluid through achillean identities. For example, an abroachillean may be a demiboy who is fluid through vincian, toric, bisexual, but is never lesbian or trixic.[1]
A more simple definition is someone who is male or male-aligned, and is fluid through identities that always have an mlm/achillean aspect, never being fluid through identities that don't have a mlm/nblm component, like trixic and sometimes lesbian.
