Learn to use SGTM in your messages By Paul Gil Writer Paul Gil, a former Lifewire writer who is also known for his dynamic internet and database courses and has been active in technology fields for over two decades. our editorial process Paul Gil Updated February 13, 2020 Artur Debat / Getty Images Texting & Messaging Email Texting & Messaging Video Calls Tweet Share Email SGTM is internet shorthand for "Sounds good to me." SGTM is an expression of agreement or a form of assent that is relatively common in online conversations between friends. SGTM can be spelled with all caps or as all lowercase, sgtm. Since both versions mean the same thing, the choice is a matter of personal preference. Be careful not to type entire sentences in all caps, as that is considered rude shouting. Examples of SGTM Use The SGTM expression, like many cultural curiosities of the Internet, is a part of modern English communication. Example 1 User 1: I can be in front of your building at 4:15 p.m. Meet me outside near the north entrance? User 2: SGTM. C U then Example 2 User 1: Instead of you driving home after work and then driving back to the southside, why not just bring your evening clothes and drive straight here from work. That'll give us more time and less stress. User 2: Hmmm, SGTM. Maybe we can hit the gym for 30 minutes before heading over to the barbecue, too. Example 3 User 1: OK, how about I vanish for an hour to drive Caleigh to the store and back. Then we can work on completing that quest together, perhaps after 7:30 p.m.? User 2: SGTM. I'll log back on at 7:30 p.m. Capitalize and Punctuate Web and Texting Abbreviations Capitalization is not a concern when using text message abbreviations and chat jargon. You can use all uppercase (for example, ROFL) or all lowercase (for example, rofl), and the meaning is identical. Avoid typing entire sentences in uppercase, though, as that means shouting in online speak. Proper punctuation is also not a concern with most text message abbreviations. For example, the abbreviation for 'Too Long, Didn't Read' can be abbreviated as TL;DR or as TLDR. Both are an acceptable format, with or without punctuation. Never use periods (dots) between jargon letters. It would defeat the purpose of speeding up thumb typing. For example, ROFL would never be spelled R.O.F.L., and TTYL would never be spelled T.T.Y.L. Recommended Etiquette for Using Web and Texting Jargon Knowing when to use jargon in your messaging is about knowing who your audience is. It's important to determine if the context is informal or professional and to use good judgment. If you know the people well, and it is a personal and informal communication, then use abbreviation jargon. On the flip side, if you recently started a friendship or professional relationship with the other person, avoid abbreviations until you develop a relationship rapport. If the messaging is in a professional context with someone at work, or with a customer or vendor outside your company, avoid abbreviations altogether. Using full word spellings shows professionalism and courtesy. It is much easier to err on the side of being too professional and then relax your communications over time than doing the inverse.
