Omniacepomo is when a person is on the asexual spectrum but is unsure where specifically, and has no preference for the gender of their partner. Omniacepomo is a combination of three different words:
Omni, indicated both omnisexual and pansexual, showing that this person is attracted to all genders/doesn't have any gender preferences. Ace indicated they are ace-spec.
Pomo is short for pomosexual 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 LGBT+ community to properly describe their identity when it comes to sexual relationships and/or activities.
Flag
The three stripes represent the three identities that make up omniacepomo. Dark purple comes from the asexual flag. Gray represents omnisexuality and pansexuality. Pink represents pomosexuality.
