A arm barn is the southern term for a circle jerk. Where a group of good ole boys get together to jerk each other off in a circle. An arm barn tends to be more rough than a circle jerk on account of all participants having blue collar jobs, thus leading to hands that know a hard day's work.
After working a hard day down at the mill, Brady was looking forward to getting together with the boys for a good old arm barn later.
