ROFL is an internet accronmym for Rolling On Floor Laughing, and like all things internet it has adapted to nerd culture and has taken on new real-life use, though usually in a satirical way.
ROFL can be merged with other accronyms to created super l33t acronyms that "r0x0r y0ur b0x0rs" per se. Some examples of the merged accronyms are as follows:
ROFLAARP: Rolling On Floor Looking At Assorted Rodent Pornography
or
ROFLEW: Rolling On Floor Laughing whilst Eating Waffles
Yo dude, these waffles are sweet! rofl. Are you ROFLEW? Nah dude! I'm totally eating them at a table.
ROfl is Fucking Lame. The word was first meant to be cool and was intended to actually express that your rolling on the floor laughing about something some dude said on the chat in your favorite game but it was soon picked up by nerds en complete nolifes. So by using the word your confirming your status as pathetic person with no social contacts except for your World Of Warcraft buddies far away on the other side of the planet.
Now by using the term in the new definition (check out examp how to use) in your favorite game you will proof to be a social guy with a very exciting life in reallife and you will get a lot of respect. Eventually with your help it will destroy the original meaning until just a small group still uses it in its original context. Then there will be room again to invent a better fresh sounding replacer for the word. Until then support me by using rofl in the new way!
Dude101:Haha he really got fucked man! his parts are all over the place!
Noob23:ROFL0wn3d!
Coolguy66:Fuck off you nolife cheater >>ROFL!
Hence the R.O.F.L
But just like every other word from the internetz it has evolved in many ways such as roflmao meaning rolling on floor laughing my ass off. It has also seemed to evolve to food products such as rofl my waffle or rofl my brothel sprouts.
