This refers to people who are both ace-spec and aro-spec (not necessarily strictly aroace) who experiences tertiary attraction that they feel is significant enough to note alongside their aroace attraction. This can be any nonsexual and nonromantic attraction.
The term was coined by @/black-aros (now deleted). A reblog of the original coining post can be found here. The original flag (the one above is a redesign by an anonymous FANDOM user) was also coined by @/black-aros. A reblog of the original coining post can be found here.
