A chick who is decent enough looking to bag, but only after several beers, is said to have a "box of arms" because of all the guys who have had those beers, done the deed, and woken up on the next morning beside her and thought "shit, i gotta get out of here bfore she wakes up". But she's laying on his arm--so he has to knaw it off. So, over time, the woman has all these guys arms, hence she has a 'box of arms'

A man so weak that his arms literally look like malnourished, out of date, shriveled up sticks of peperami. You all know him, the guy who pays the PT in the gym and lifts those miniature girl weights, eats chicken dippers at 10am every day thinking he's making gains when actually all he's doing is pooping those gains right out.
That guy from the gym Adam B, look at how puny his arms are, i've seen more muscle on a tad pole. If there was a international competition he would be the Mr Olympia of peperami arms.

when one is on mdma and can't stop moving their arms in various waving patterns while dancing, as if they are swimming through the air.

The unbendable arm is when you put your right arm on someone else's shoulder and without flexing, have someone push down on your arm. If done correctly, your arm won't bend...
If you happen to be brave and have a tough arm, then you can have someone hang from it, and do pull-ups if they're up for it
