What you get when you connect to your neighbor's wireless (or wired, for that matter) internet, with or without his or her knowledge.
Didja hear? Johnny connected his wireless ethernet card to his neighbor's wireless network, and now he's got neighbornet!

The internet you get when mooching off of a neighbor's wireless connection, as opposed to just the regular internet you get directly. Unlike the regular internet, the neighbornet is slower, and dies randomly, but it's free.
"Shit, brah, my router's busted. I'm stuck checkin' Facebook on the neighbornet coming from the guy across the hall."
