Sass Approved

Maybe not SASS, though.

One of the unique aspects of SASS approved Cowboy Action Shooting™ is the requirement placed on costuming. Each participant is required to adopt a shooting alias appropriate to a character or profession of the late 19th century, a Hollywood western star, or an appropriate character from fiction.

Emphasis mine. Who's to say what's appropriate?

Brazenly rustled from Mad Ogre.
