laughs or LulzSec
When spelled in all lowercase, lulz primarily stands for "laughs" or "laughing;" when capitalized, Lulz refers to members of the media-savvy hacking collective Lulz Security, or LulzSec who publicly announced in 2011 that they had successfully hacked the websites of the CIA, the U.S. Senate, Britain's Serious Organized Crime Agency, Sony, PBS, and other high-profile targets. And while LulzSec came to embrace politically motivated hacking, they also hacked sites and disseminated stolen information just for the "lulz," or laughs.
Online jargon, also known as text message shorthand, used in texting, online chat, instant messaging, email, blogs, and newsgroup postings, it is spelled in all lowercase because it's also considered a form of leetspeak.
