Officesticated

An individual who has been working in an office so long they have forgotten what it's like to not be tied down by the 9-5 workday.

Very similar to the domestication of a man or woman after marriage.

Young Employee - "Why does Derek only speak in cheesy office Clichés?"
Older Employee -"He's been here too long, guy's been Officesticated..."
Young Employee - "Damn, I hope that's never me"
