arm test 

The premier method to determine whether a woman is a chubster or a non-chubster.

Look at the upper-arm and determine if there is excess skin/flab/meat between the bicep and shoulder - if there is excess skin/meat/flab and she is not a body builder, then she is a chubster.

It was created as a result of women becoming social media sorcerers in that they can mask any and all fat.

"This girl on Tinder is doing that skinny arm trick, I can't tell if she's a McFatty." "Apply the arm test, bro."

Big arm test

A big arm test is a visual check of the diameter of a girls arms to determine if she will blow up in the future. If a girl has large arms but a small body while young, chances are she will become fat in the long haul.

person 1 - "damn, look at that girl on the beach, i'd marry her!"

person 2 -"nah dude, she fails the big arm test, shes gonna blow up like a blimp"
