A feared helicopter that flies around looking for unsuspecting victims. If you are shot by a ROFLCOPTER, you will forever be turned into a blubbering idiot that does nothing but roll on the ground and laugh.

Tom got shot by a ROFLCOPTER and now all he does is ROFL all day long, just like the kid in "ROFLCOPTER: The Movie"!

Invented by a Blizzard moderator on the Warcraft III forum. There is always much whining going on on those official forums, much sucking up to moderators and an awful lot of 'BLUE!!! PLZ REPLY!!!1one' (Blue = color of moderator posts), so when a mod posts something, you can bet there'll be thousands of people jumping on it, if only to spam 'BLUE FIX GARGZ PLZZZZ' or 'first reply woooot!' after it in the vain hope that the mod will read it and react.

So when one invented this new buzzword, it was grabbed and squeezed out and spread like a virus across all of the Blizzard forums and from there over the internet.

The word is derived from a unit in Warcraft III, the gyrocopter (flying machine). Your immediate response when someone masses gyros (to be funny, ruin the game, mess around or whatever) is to rofl for ten straight minutes until the copters of doom and destruction have pinpricked 1 of your 20 farms to death with their uber godly bombs.

Now mostly used in Blizzard circles as a leeter version of rofl.

The superior being of chatspeak, 'roflcopter' out takes down all lollerbladers, lmaoplanes and various other outlawls. Pilots of the roflcopter often enjoy a nice crispy ZOMGBBQPIZZA and some lolmonade. Children also enjoy a good ride in the roflcopter, as it spreads smiles and festivals known as the 'lolapalooza' across the world.
Captain Sloloman of the elite omega roflcopter squad enjoyed a fresh ZOMGBBQPIZZA and a cool lolmonade after his swift victory over the lollerbladers, lmaoplanes and outlawls and returning safely to the lolapalooza.

Based of an ASCII picture and now a flash game. The rofl copter has its spinning LOL propellers and occasionally drops a WTF bomb or an OMG missile and the LOLerskaters below or the LMAO planes.

2. Response to an incredibly funny statement.
