SMS language

SMS language is shorthand or slang words and phrases when typing SMS or text messages on phones and other devices. That way you can type messages faster and use fewer characters to say the same thing. For example, 'lol' means 'laugh out loud'. 'BRB' stands for 'be right back'. It's a type of code language that helps people communicate quickly and effectively.
