the switch back

The process of switching from one female to the other through sexual intercourse. Whether it's oral, anal, or vaginal, the females must be on each other or close by in order to complete the switch back fast enough.

Sarah and Tina were laying on top of each other kissing, while Jim was preforming the switch back on both of them.

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.
