Commonly called bingo wings or upper arm fat, Sludge guns are when the area on a woman's upper arm between the elbow and shoulder are fat or chunky.
Even thin women can be inflicted Sludge guns.
When I'm at the beach I get sick and dizzy feeling because of all the sludge guns.

I went to bingo with my aunt last night...It was sludge gun mania!
