To share files at a computer network meeting (or LAN party).
Its the nerds way of saying "hook a brother up".
Rather than burn a tonne of dvds and cds worth of good stuff, just transfer it over the network (or leech) at the next LAN gathering, before playing an epic session of games.
person 1: "I have 20 new release dvd rips on my computer."
person 2: "nice one.... LAN it up."
