It's the state of being when you do something very very well. Particularly at a sport, like in Soccer when you score a goal and you do a dance and scream, "I'm on FI-YAH!"

Hey Joe, remember when you logged countless hours as a post-grad in computer science helping to create some foundation for the internet? Well your efforts shouldn't be in vain, we're now hooked up with interface wirelessly and calling it Wi-Fi.

A subgenre of Science Fiction (Sci-Fi) consisting largely of "near-future" science fiction films made in the 1990s. Shares significant overlap with cyberpunk but is somewhat more broad and mainstream. The films are the product of the recognition of the '90s populace that the digital future was coming, but the means of portraying that future onscreen were largely analog. CRT monitors everywhere, use of tapes, ubiquitous bright colors, and a conspicuous lack of the amount of film filtering and CGI that permeates 2000's sci fi films.
The Lawmower Man 2's future full of CRT monitors and crappy bluescreen work gave it a real Ni-Fi mood.
