nasty nose syndrome

a compulsive disorder wherein an individual is compelled to constantly be involved (directly or in an ancillary capacity) in OPB (other people's business) and somehow manages to bring out the worst, or highlight the negatives in any given piece of information, and MUST pass the news along to at least three other people.

Cubicle deskmate to "new girl" in the office: "Be careful about Phyllis, don't ever say a thing around her. Bless her heart, she suffers from Nasty Nose Syndrome."
