Office Grazing 

Office grazing is defined as the art of strolling between cubes and offices conversing with co-workers as to avoid doing actual work. The key is to be ambiguous in your grazing as to not draw attention to yourself. Avoid consistent high volume laughter or complaining while office grazing.

Bob and Cindy were nice people but their incessant office grazing got them both fired because they were always heard complaining and laughing about the same things to seven different people located within 10 feet of each other.
