Moses Arms

A common phrase used when measuring the size of arms that are below average size or lacking bone marrow. (Usually from a life long disease or lazy lifestyle) A person with said arms will never make gains.

Look at the new guy coming into the gym, he's got a long way to go with those Moses Arms.

strong arm machine

The Strong Arm Machine or SAM is a large and powerful robot from the game Jetpack Joyride that can take 3 hits from missles which it has to deflect with a arm-mounted force field. It also has some kickass music.

I have to wait another 24 hours for a chance to get a strong arm machine.
