The adult life and workplace equivalent of "teacher's pet". Generally is quite an astute and talented person work-wise (male or female) and does any thing - any - thing - from wiping the boss's arse to drafting acquisitions proposals, preparing presentations, ratting on fellow employees, to doing complex mathematical analyses.
However, is an idiot in personal life and doesn't ask for money worth his work and usually is abused by more than just the boss.
