Omnipanflux is a term for when one feels that they fluctuate between pansexual and omnisexual identities. This can also include fluctuating between omni- and pan- romantic, omni- and pan- aesthetic, etc. Someone who is omnipanflux may feel that gender plays a role in their attraction one day, but doesn't the next.
The term omnipanflux was first used in May of 2021. It was later coined by the user https://lgbta.wikia.org/wiki/User:InkMink on June 1, 2021. The flag was created the day before by user https://lgbta.wikia.org/wiki/User:EnnelieSPF
The colors on the omnipanflux flag do not have any set meaning, but are designed to act as a mix between the pansexual and omnisexual flags.
