It includes everyone, and sometimes almost literally and their mama.
Person 1: I told you what happened in confidence you would keep it to yourself but you ran around running your mouth to everybody and their mama

Person 2: it sort of slipped out, I'm sorry!

Get the everybody and their mama mug.
A more appropiate informal, better sounding way to say "everybody and their mom" (which is grammatically correct but just sounds a little bit too white LOL)

An expression and metaphor used to explain and complain about the excessive amount of people in a location.
Why is everybody and they mama at the store right now?! Go home and order a fucking pizza!!!

Dang everybody and they mama was at the washhouse today, I had to go way down the street to the other one.

a reason that I'll tell you what you should be doing even if I have never seen you before
I mention to a stranger, "Your shirt's not buttoned right," or at a local restaurant, I'll suggest what he should order for lunch, and add, "anybody's mama, everybody's mama."
