Now, in general, there are times "text" lingo can come in quite handy. That being said, there are also times when it is infuriatingly obnoxious.
Right Times to Use "Text" Lingo
1. Texting: People who are on pay as you go plans and have to pay per text, or people who have limited characters they can use, it makes sense to abbreviate words in any way possible
2. In a hurry: OK occasionally, you are in a really big hurry and need to leave your computer quickly, in which case some "text" lingo is understandable
3. Tablets: Tablets may give you unlimited space to type versus cell phones, but sometimes the keyboards are obnoxious so I can deal with some "text" lingo
Times "Text" Lingo is SO Not Cool
1. Generally any time that the above is not the case, you are on-line, not in a hurry, at your keyboard, the constant over use of "text" lingo just makes you look dumb and sound uneducated
2. In every day speech: I have actually heard people say L.O.L out loud in regular conversation. I've also heard O.M.G. used as well. People, "text" lingo is for "texting" or at least being at a device that requires actual typing. Using it in every day speech is not only insanely annoying, it makes you sound like a complete idiot.
