What does MBS stand for in online chat?

Mom behind shoulder

If you're a mother, and you see your child enter MBS in online chat, you should circle back to have another look at their screen. This acronym, which stands for "mom behind shoulder," is a common warning children use to let others know their mother is around. (And thus, no one should say anything inappropriate.)

MBS is just one of many acronyms and codewords children use to warn others that their parents are around, while engaging in online chat. Others include CD9, C9, POMS, and DBS.
