The shippiest thing I have ever seen on Wookieepedia is in the entry for the Open Circle Fleet, about the open circle symbol:
The heraldic emblem consisted of a yellow circle that was formed by two separate semi-circle arcs. One arc represented Kenobi, the other, Skywalker. The image signified that while they were both two independent halves, together they formed a single entity.
I believe it was matching tattoos and their validity in the face of the Council’s disapproval.
We are not 100% sure.
It’s like having friendship bracelets, except instead of just wearing them, they have a symbol on their armor and their ships and random landing platforms and basically plastered everywhere for the galaxy to see.
What the. Now this is a totally legit headcanon now.
