The Arm 

When you're cuddling laying down face to face with someone, and you don't know where to put your arm...as it sits awkwardly between you two.

The Arm of '82 

Legend has it, back in 1982 in a factory located in Southeastern Wisconsin, an unknown person took a shit so big it would make your asshole pucker. Unable to flush the mighty shit, it was simply left in the stall until it was discovered by factory workers. The legendary shit was said to be as thick as someones forearm and stood erect above the bowl with its tapered end bent over much resembling the head of the Loch Ness Monster. To this very day, no one knows who made it...

The arm rule 

A way to know if you need a condom size bigger than medium. By measuring your penis to your arm, if it's bigger then you need a bigger size.

Hey dad what size condom should I wear? You should use the arm rule. Oh ok

Yawn-And-Put-The-Arm-Over-The-Shoulder Manouver 

The cheesiest move a guy can ever do. ever. You yawn, and lift up your arms in a streching move, then put your arm over her shoulder. One of the hardest moves to pull off.

I saw a guy do the Yawn-And-Put-The-Arm-Over-The-Shoulder Manouver in france next to the eiffel tower before, and I wanted to go and shake his hand. But I didn't want to ruin the moment.
