Rare skin condition that affects one in seven geeks born before 1982* caused by unreliable CRT monitors exploding inexplicably in one's face. The resulting scabs often form in a regular pattern resembling scales, hence the moniker, Lizard.
Monitor Lizards were generally regarded with fear and awe by the geek and hacking communities until the mid-nineties when it became fashionable to sport a 'monitor print' by deliberately exploding a monitor on a person's head.
After the loss of its influence as a status symbol, the Monitor Lizard gradually faded from the annals of history and time past.
(*Information accurate as of June 1990. Although some dismiss the Monitor Lizard phenomenon as an urban legend, 72% of all seven year olds surveyed attested to the story's validity.)

"Fo shizzle mah nizzle. That was a gangsta monitor lizard fo' real."
One of those humans that sits in a room simultaneously monitoring multiple monitors arranged in a large panorama around the viewing chair, displaying a range of input sources such as the news, sports, cable tv shows, video games, porn, security cameras, etc.
For those that prefer to not disconnect from one channel to surf to the next on a single screen, but "parallel process" all of it by flitting attention back and forth between a dozen screens, information overload to the point of total saturation.
Especially popular with media/news reporting and intelligence/security ppl.
Some do it for a career, some do it for entertainment, some need to be completely distracted from reality.
