"I also heard of the term "gun show" to mean a bunch of people (yes, both men and women) showing off the size of their biceps. I'm just curious because I don't think any other muscle or muscle group has a far-fetched term. Trapezius muscles are traps for short. Triceps are tris for short."

- When did guns become slang for biceps?
