Texting, instant messaging, and emailing on the Internet have had a big impact on how people communicate.
Shortened phrases and words and widespread use of acronyms have become very common as people have found ways to type text quickly without having to enter long words and phrases. Internet slang has also become firmly embedded in the way people communicate, even if you're not using a router to get your message across. Slang and acronyms also help people express emotion via written text, which can be hard when you can't see someone's face or hear their voice. Learning popular Internet slang can help anyone communicate more quickly and efficiently online.
