e.g. SKillMaN left a small crater. Everyone on Vent: ROFLCOASTER!!!!!!

roflcopter 

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.

'...and this guy said I could reduce lag by up to 100% by hitting alt-F4. I did and the game closed on me. This is griefing, admins plz ban'
'ROFLCOPTER!!!!!!!!!!'

Roadcoaster 

when riding shotgun with somebody, who, just for a split second, takes their eyes off the road, looks back and realizes they drifted 2 feet out of their lane and proceeds to jerk the car back in to position so violently that your neck suffers whiplash. just like riding a rollercoaster, it can also be done in smaller jerks that, by the end of your ride makes you look for the first bush to purge behind.

boy #1 -dude, you just see a ghost?
boy #2 - no bro, i rode shotgun with Becky in the roadcoaster!
boy #1 - oh, shit..bathroom is down the hall, 1st door to your left!

roflcopter 

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.
