While performing a manual labor job, you find that the undersides of your arms are dirty and you didn't even realize it.
"After a long day setting up my concession stand at the fair, I had some serious carny arms going on!"

When I reached across the dirty roof of the car to toss my friend my keys, I noticed carny arms and had to go wash up before going back out."
