Aromanticism

Aromanticism is a romantic orientation referring to people who experience no romantic attraction. Aromantic is often abbreviated to "aro." Aromantic is often considered part of the aromantic spectrum, which includes other identities such as grayromantic, demiromantic, and many more.

The Flag
There are many different versions of the aromantic flag, though the most commonly used flag has a dark green stripe, a light green stripe, a white stripe, a gray stripe, and a black stripe, from top to bottom. The dark green represents aromanticism, the light green represents the aromantic spectrum, the white represents platonic and aesthetic attraction, gray represents gray-aromantics and demiromantics, and the black represents the sexuality spectrum, showing that aromantics can be of any sexual orientation.

The green could also represent the opposite of romance since green is the opposite of red (and red also happens to be the color most commonly associated with romantic love).

Attraction
Aromantics can be attracted to any gender, depending on the person and their other orientation(s), whether sexually, platonically, sensually, or aesthetically, but not romantically. This means aromantics can be attracted to people, however they typically don't want to pursue a romantic relationship with anyone (this is not the case with cupioromantic people).

Aromanticism and asexuality are different. Aromanticism is the lack of romantic attraction, and asexuality is the lack of sexual attraction. Although some people are both aromantic and asexual, not all aromantics are asexual and not all asexuals are aromantic.

Aro Ring
In recent years, some aromantic people within the online AVEN community have proposed that there be a white ring for aro people to wear on one of their middle fingers to symbolize aromanticism, as opposed to wearing a ring on their marriage finger. This seems to be a direct response to many asexuals wearing a black ring to symbolize their asexuality.

Aro
An informal term, short for "aromantic." The plural is "aros." Pronounced the same way as the word "arrow," which is considered to be quite fitting since arrows are seen as symbol associated with romance (i.e. Cupid's love bow).

Ace of Spades
Ace of Spades is an aro/ace slang term used for an aromantic individual who is also asexual, meaning they don't experience sexual attraction.

AroAce & AroAllo
AroAce is the abbreviated version of "Aromantic Asexual," referring to those who are both aromantic and asexual. AroAllo is the abbreviated version of "Aromantic Allosexual," referring to those who are aromantic and allosexual. An allosexual is someone who isn't asexual.

GreyAro & DemiAro
GreyAro is the abbreviated version of Grey-Aromantic or greyromantic, referring to those who experience romantic attraction that is in the grey area between aromantic and alloromantic. DemiAro is the abbreviated version of Aro-Demiromantic or demiromantic, referring to those who cannot experience romantic attraction until a bond has been formed with another person.

Squish
An aromantic equivalent of a crush, usually one that is experienced in a platonic or queerplatonic way.

Terminology
The word aromantic is a combination of the prefix a-, meaning "not" or "without", and the word romantic, meaning to have love or affection (note: aromantics can still feel love, just not the romantic kind). While the word aromantic didn't exist until about the mid 2000s, there were other words to describe the aromantic experience, such as non-romantic, and asexual, as well as others.
