I know him well.
You can spot "that bloke" coming a mile away. He'll be the one that jumps.
Everywhere. He. Goes.
He jumps in Ogrimmar.
He jumps in Darnassus.
He jumps in Ironforge.
He jumps in instances.
He jumps in duels.
He jumps in trades.
He jumps when he's mining.
He jumps when he enchants.
The <censored> even jumps when he's afk.
And oh boy is he in jumping heaven when you join his group. Bouncy bouncy bouncy, like the Ever Ready Bunny jacked up on meth, stopping only to grace you with classics like "lol hve u got ne wool" or "my bro kiled tha tree in ashenval". It's a difficult choice.. would I prefer him to engage me in this heady intellectual dialogue, or just watch him jump for an hour?
I saw who I consider to be some sort of Elite Jumper in Ironforge last year. Perhaps he was the King of Jumpers, I dunno. But that guy had it down pat, he barely touched the floor, so graceful was his space bar adventure. He'd mapped a cry and laugh macro and targetted me while i was at the auctionhouse. Bounce bounce bounce, lol, lol, lol. Bounce bounce bounce, cry, cry, cry. The following week, I saw him again, in Ironforge doing the same thing to a bunch of people by the Postbox.
I hate the jumpers with a fiery passion that would melt faces.
