LMO has 2 meanings
1. What does LMO stand for?

Let's make out

If you are attracted to a person and want to kiss someone, you can send them "LMO," which stands for "let's make out." However, be careful who you send it to because it is an incredibly forward prompt that may scare people off.

Most people use LMO when texting or messaging online in a private chat. For example, a bf may text his gf during school lunch, "Meet you under the bleachers in 5 mins. LMO."

While people typically use it with people they know well, some creepers may send it via DMs on Twitter or Tinder. If you want to shake off unwanted advances from creepy guys, simply reply with "Ew, gross" or "GTFO."

2. What does LMO stand for in online chat?

Leave me one

Chatters who are AFK may use LMO to mean "leave me one." You're most likely to encounter this acronym in a user's Away message, meaning "leave me a message if you'd like."

When the user who posted LMO returns to their computer, they'll likely respond to whatever message you've left them. If your message is urgent, be sure to say so, by telling the user to respond ASAP.
