Top Definition
An intense office plague that spreads rapidly to co-workers in spite of little to no contact with Dennis. Some people may not even be within the vicinity of the department or state and yet still be stricken by this mysterious virus. The virus is known to last over two weeks and sometimes over a month. It has similar symptoms to the common cold or flu with exceptionally increased mucus production, extreme sore throat and urge to cough. You would probably get rid of herpes before the Dennis.
I don't know how he did it, considering I haven't seen him in 2 weeks, but I'm pretty sure I have the Dennis, and I'm losing my will to live.

I think I contracted the "Dennis" again.
