If you’ve ever been into an online chat room, used an instant messenger, had a conversation via text message, or talked to a teenager, you are probably at least somewhat familiar with many of the following texting abbreviations. Although they tend to be grammatically incorrect and slightly confusing, they are commonly used and practical, making sending text messages quick and easier on your fingers. You don’t have to use them if they make you feel like you’re losing IQ points, but chances are that you will have to decipher them at some point if you haven’t already, so the least you can do is know what they mean.

This abbreviation is an addendum to a jocular or sarcastic statement. It is used to clarify that the statement prior was in fact meant in jest.
Use as a stand-alone statement to bid farewell or in conjunction with “c u” (see you).

Another stand-alone expression, “lol” can be intensified by using capital letters (LOL) or adding exclamation points.
A stand-alone expression conveying any combination of disbelief, frustration, anger, fear and/or confusion.

There are also what we call “emoticons” (emotional/emotive icons). Generally, emoticons are simply combinations of keyboard characters that, when combined, resemble an expressive human face. Here are a few examples:
Maybe you are one of those people who can’t stand all these nonsensical texting abbreviations and symbols. Maybe you will insist on spelling out every word and using correct capitalization and punctuation until the day you die. That is perfectly acceptable, but at least now you’ll be able to decipher what everyone else is saying.
