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.

skinny arm trick 

A trick girls do in photos to hide the fact that they have fat arms.

It is performed by placing a hand on your hip and angling that arm with your body, like a "teapot".

I wasn't sure if that girl on Facebook was fat or not until I noticed she was doing the skinny arm trick in every photo.

armskin 

Ornamental human skin decorations such as drawings, bracelets, arm and leg bands tightly worn to cover and adorn the naked visible skin of human beings.

I like the shape and color of your armskin.
