The term was coined by Reddit user __3Li_ on September 7, 2021. The flags were created by the same user on the same day. It was originally coined as genderferal/bastardgender; however, the name was changed after finding existing terms with those names. The name was changed again after being suggested by Reddit user pavlov_pvppy on September 8, 2021.
The bastardcoric flag is made up of bright colors, dull colors with an orangey-brown tint, and a white stripe in the middle. On the first and main flag, a middle finger emoji is in the center, signifying one's bastard-like nature. The bright colors represent one's outgoing and wildly open gender, the dull colors represent one's funny-horribleness towards anything relating to the oddness of one's identity, and the white stripe represents the lack of caring about other things, such as one's gender identity in this case.
