MOS

What does MOS stand for in online chat?

Mom over shoulder

In online chat, kids sometimes use MOS to stand for "mom over should." This acronym is a heads-up that the sender's mother is in the room with them, and can read their chat conversation.

Most often, kids use MOS to tell those they're chatting with to avoid inappropriate subjects and swears, until their mother goes away. So if you're a mother, and you just stepped away from your child's chat conversation to look up MOS, you may want to go back and see what your kid's talking about now ...

Example

Chill on that for a min, MOS
K, cool. Whatchu wanna talk about then?
