intergnat
An annoying person that hovers over you and watches what you're downloading on the Internet, usually at an Internet cafe or at a library. Does not necessarily have to be a person in authority---could be a nosy kid, impatient person that's next on line to use the computer, etc.
I wish I had my own PC at home. I always get an intergnat or two when I use the 'puters at the library!
