[Just another Joe]

I forget the rules as I've never had a pierced ear...left ear means your gay and right ear means you swing, or is it the other way around? (grin)

Neither.
I have my right ear pierced.
The reason I have my right ear pierced?

Most people are right handed. When in a fight, they swing with their right hand.
A roundhouse would hit my left ear.
I only wanted one hole in my earlobe, not a bunch of holes in the left side of my neck from the post.

In Tang Soo Do (and other martial arts), they teach us to be proficient with both hands and feet. A fighter with those skills and knowledge will go for the weakest part of an opponent. In your case, it is your right ear.
