'LOL' or laugh out loud, the popular acronym used by net chatters has undergone a change and is now replaced by a supposedly cooler acronym, 'PML'.
And no one still uses BRB (be right back) - it's BFN (bye for now).
"I can tell someone's age from their internet talk. When I read BRB or LOL, I think, 'Jeez, that's so old,' " the Daily Telegraph quoted social media expert Laurel Papworth as saying.
Instead, techno-savvy bloggers are using PML and BFN. Also popular is NSFW (not safe for work), which the University of Sydney lecturer said is used as a warning when the attachment is "somewhat vulgar".
And TL;DR (too long; didn't read) means the status update is too long and the person couldn't be bothered to read it.
"More mums and dads are getting on Facebook, which means the language is quite tame, but on Twitter users have to express themselves in 140 characters or less, so people have created all these new phrases," she added.
