So I found out there was no term for this so I made my own up!
Versionshipping
Definition: A self/yumeshipper who only self/yumeships with one particular version or iteration of their f/o and is not linked to or self/yumeshipping with other versions of their f/o
Flag idea
It's not perfect but it'll do for now ig
I chose the name because its straightforward and its true for me
I versionship with OPLA Sanji, MCU Bucky, MCU Loki, Looney Tunes Show Lola Bunny, Voltron: Legendary Defender Lotor & 90s X-Men Animated/X-Men '97 Erik Lehnsherr
Any other versions of my f/o's listed are not whom I yume/selfship with
I have coined the name but lemme know if there is a better alternative as well as flag design!
