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.

From the term rofl (Rolling On the Floor Laughing), roflcopter describes rolling on the floor laughing so hard your legs begin moving, causing your horizontal body to turn in a clockwise (or counterclockwise) motion, much like the rotating blades on a helicopter.
Wow, that was so funny I actually roflcoptered.
