Learn English – When and from where did “guns” become slang for biceps

etymologyorigin-unknown

I first heard the use of guns to mean biceps in high school. I thought it was just a local slang. It turns out to be universally known. I later saw it in magazines and fitness books. 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. Quadriceps are quads for short. Why are biceps guns? It doesn't make sense and seems so remote from the literal gun.

Why are biceps guns? It doesn't make sense and seems so remote from the literal gun.

It's actually not that remote, if you work in reverse. Arms has a common meaning of weaponry in English. If you were to say small arms you would be specifically referring to guns. Which is funny when you think of the irony.

I found a partial answer on the Straight Dope message board.

The baseball origin is probably correct, according to Lighter. As early as 1929 the NYT was writing "A player's arm is his gun or his wing. A good gun means that the possessor has a strong arm.

That message also includes this snippet:

Then a quote from something in 1973 "Guns--the biceps and triceps part of the arm.

I wasn't able to find a source of that quote, but I did find this from a book published in 1990, but according to the author's website was started in 1979. Some Dance to Remember: A Memoir-Novel of Gay Liberation in San Francisco 1970-1982 by Jack Fritscher.

I found a reference to “Does he have guns like these?” as a quote in a 1989 episode of Married With Children.

I haven't found a direct link from baseball to bodybuilding, rather I suspect the link begins with "pumping iron".
