It can be difficult to decide if that dude or chick is on meth, has chicken pox, or simply has bedbug arms, but a look at the unbitten face clears up any fear about meth or chicken pox.

waving your arms around in an entertaining fashion to confuse your fans and make them think you can still dance.
1: Did you attend The Circus Starring Britney Spears?
2: Hell no, I'm not paying $100 to watch her pass off her arm flail crap as dancing for an hour and a half.

The scientific theory that allows a male to determine a female's figure and/or bodytype based solely on the size, shape, and density of her arm. The male is able to determine whether she is fit, skinny, fat, or even skinny fat based on a single glance.
If her arm is super thick but she still has a pretty face then Arm Theory states that she is better labeled as "fat" and not as "pretty."
