1. A slang term combination of "ROFL", (meaning "roll on the floor laughing"), with "berry", to make up a humorous and fictional new word, much like "Snozberry", coined by the original Willy Wonkey movie.
2. Not only is it a berry produced by the infamous LMAOBUSH, but it is a delicacy among those who are known to pwn all teh nubs. Those who are 1337 enough to convert these delectable berries into n00b sauce will find that they become the staple to the most leet of diets. Beware, as excessive consumption of such a delightful fruit could result in the eater getting h4x0red, and the uncontrollable yelling of "LOL !!!!!!!!1!!1!". Warning, do not eat while operating a ROFLCOPTER, while wearing LOLLERSKATES, or while firing a n00b-cannon.
"You are not even in possession of a single, lone ROFLBERRY?"
"Well. I'll just be on my way then I think."
