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.
