Get the Lash Backmug. 
The un-recognised medical condition for tall people who spend most of their time at work bent over a paper trimmer 2ft too short for the operator to use. The resultant injury from standing over such a device after more than 15 mintues is dubbed 'Trimmer's Back'. A back injury for Office Supplies workers.

Get the Trimmer's Backmug. 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.
