cottage back

A seasonal medical condition that arises on a Monday after or a Friday prior to a nice weekend in the summer in which the reported back pain is directly proportional to the sunniness and temperature outside; results in one’s inability to come to work on the affected Monday or Friday and he/she having a three-day weekend that is likely spent drinking beer on the dock at his/her cottage or cabin while his/her co-workers pick up the slack back at the office.

My co-worker came down with cottage back; it prevented her from coming into work last Friday, and when she came in on Monday, her back was fine, and she also had a tan.

fully backed

Your parents have your back. They are helping to support you. You are your own person...with the help of your parents.

I've graduated from college and now I'm on my own...fully backed.
