Arm Plunt

It's when you take a tennis ball and you open up your arm and you put it in and then you stretch the skin over it and sew it shut. It then heals over the tennis ball to make it look like you have muscles.

Damn, Arin! Where did you get those muscles?

Oh, these are just my arm plunts.

Suitcase Arms

Someone who doesn't swing their arms while they're walking, but keeps them straight up and down, thus it looks like they're carrying suitcases.

Did you see that new secretary in the office? She would be totally hot if she didn't have a major case of suitcase arms.

weird arm

When you're laying in bed, most likely with your boo, & your arm is either under or around them & it's awkward or going numb. &/ or your boo could be lying on their own arm strangely so that you can be super close. You'd say "babe can we move, I've got weird arm".

I love spooning you, but can we switch? I've got weird arm.
