Aro Neu or Neu Aro (expanded to Neutro Aro or Aro Neutral) describes a person on the aromantic spectrum who does not label their sexuality. They are neither allosexual or on the asexual spectrum. It was proposed by Tumblr user A-romantic--aromantic on May 19, 2019.
The term is intentionally vague and includes non-SAM aros, unit aros, aromantics who don't know if they experience sexual attraction, and aromantics who can't tell the difference between sexual attraction and other types of attraction. The term can be expended to neutrosexual for those who want to.
Aro neu is similar to, but more specific than the term quoisexual.
The aro neu flag shown above was proposed by Tumblr user A-romantic--aromantic on May 20, 2019. The top half uses the same green stripe gradient as the aromantic flag. The bottom two stripes are a neutral mauve, which is in between gold for aromantic allosexuals and the purple for aroaces.
