Chatspeak is the term used for abbreviations and slang commonly used in electronic communication, including text messages, email, and instant messaging. It most commonly comes in the form of letter homophones, such as “LOL,” or onomatopoeic spellings, like “haha.”
An advantage of using chatspeak in written communication is that it is faster and easier to type or write. Instead of reading paragraph-long texts, people are able to read and transmit shorter texts. That was the goal of many writing classes, right? To be able to communicate in a clear and concise manner? “TL;DR,” which stands for “too long; didn’t read,” was coined as a satirical reference by the Something Awful forums in the early 2000s as a means to say “You are too wordy, shut up and go away.” In short, if the message is too long, it won’t get read.
Besides, these acronyms build character and show how culturally adept people are with electronic communication and the Internet. Sure, it can come across as inappropriate in specific environments, like the workplace, because of its casual usage online. However, mature and professional people would truly know how to act and not let slang affect their level of literacy.
Bottom line – GWI.
(& If you didn’t understand that, I insist on memorizing this entire list of chatspeak ffs.)
