Job Douche

Someone who gets really involved in a job and lives for the weekend

Guy 1: Hey, shall we go see Transformers on Tuesday night? That new, admittedly horse-like replacement for Megan Fox will be adequate for me to part with my cash to see that sub-standard movie
Guy 2: Yeah man, I'll invite Tim, I always enjoy his witty and insightful comments
Guy 3: He has to work on weekdays. He's a job douche now.
