Lulzcopter 

By far the fastest copter yet. Completely destroys the roflcopter in everyway. Has the ability to do battle rolls and contains mudflips. It also has two floppy disks. It has the ability to break the speed of waspeses. Surpassed only by the lulzjet.

Tim-"Oh shit it's the lulzjet!!!!"
Bob-"Hurry get to the lulzcopter!!!!!"

Winston: Hey, did you see that YouTube video of that 12 year old who screamed "I'M NOT A HOMO!"?

Hajji: Yeah dude, he's a total lulzcow. The commenters on his videos are getting exactly what they're aiming for - his rage recorded on the intarwebs, complete with fair use laws to let them download his video and "remix" it, which infuriates him more.
