ROFLCon

ROFLCon was a biennial convention of internet memes that took place in 2008, 2010 and 2012, featuring various internet celebrities. All three events were at the Massachusetts Institute of Technology. ROFLCon was first organized by a group of students from Harvard University led by Tim Hwang. According to Hwang, the inspiration for the conference was the September 23, 2007 meetup of fans of "xkcd" with its creator, Randall Munroe, in a park in North Cambridge, Massachusetts.
The name "ROFLCon" comes from the internet slang "ROFL", short for "rolling on the floor laughing", and "con", short for "convention".
At ROFLCon 2012, it was announced that there would not be another ROFLCon.
