Three years ago, we already had a thread about what acronyms we would consider as memetic on the internet. Old as well as new threads were made to discuss that peculiar subject and there are still people wondering about peculiar acronims as being valid for an entry. As time went by, many single entries about specific acronyms and initialisms popped up, such as lol, omg, wtf, gtfo, gg and a plethora of others.
I think it would be a great idea to have a list of the many different acronyms/initialisms that haven't their own entries yet.
As you can see, there have been attempts at threads that eventually became locked due to inactivity. Let's try to not let it happen to this one, shall we?
For instance, I'm thinking about IMO (In My Opinion) that has been used for years, spawning a more formal form as IMHO (In My Humble Opinion).
