Drummer Arm

When one of your arms is bigger than the other. Usually your dominant arm.

"Hey Jack, your drummer arm is awful!"

"I know bro, my left is so much larger than my right."

Skinny Arm

A pose that the modern woman assumes in photographs to diminish the abundance of flab on her inner arm.

To give the deceptively casual appearance of a well-toned extremity, a female will place her hand on one hip, bending the elbow at a near-90 degree angle to prohibit excess fat from collecting next to her torso.

I had to untag that picture because I looked like I was about to ship out to fat camp; I forgot to strike a skinny arm.

Even out of shape men can rock a nice skinny arm.

Monkey Arm
