Funnel or Funneling is an expression also used in the world wide popular MMORPG "World of Warcraft". The consept of the word was invented (as story is beeing told) by Exellia and Ljungfrau on the pvp server Vashj. The best place to preform a funnel is in the Draenei city "Exodar". To do this you need a mage, simply for the ability they have to make portals. What you do is create a portal behind the place where you will end up if you take the portal. Line up as many people as possible. Run towards the portal click it and you will end up where you started. Do this rapidly over and over again. It's hillarious.
