An individual who replies with an unusually high frequency of overly used acronyms, and is always one of the first five individuals to comment on any content posted to social media websites.
A member of the baby boom generation that has finally discovered acronyms and uses them at any given opportunity hovering, much like a helicopter, waiting to drop in on your Facebook wall with a ROFL.
Steve's girlfriend is a roflcopter. She always comments LOL, OMG,LMAO,or ROFL to every picture I post. She's so dumb and unimaginative she can't say anything else, and has nothing better to do than to comment on my FaceBook Status
