Omniaropomo is when a person is on the aromantic spectrum but is unsure where specifically, and has no preference for the gender of their partner. Omniaropomo is a combination of three different words:
Omni, indicating both omniromantic and panromantic, shows that this person is attracted to all genders/doesn't have any gender preferences. Aro indicates that they are aro-spec.
Pomo is short for pomoromantic and indicates that they do not know, or care to label themselves more specifically, and/or because they feel there is not currently a term within the LGBTQ+ community to properly describe their identity when it comes to romantic relationships and/or activities.
The asexual counterpart is omniacepomo.
