The look you get when your boyfriend/girlfriend introduces you to their mom and you see the look of disapproval in her eyes.
I think my mom really likes you.....

When you wife or girlfriend gives you that same look your mother used to when you were in deep doggie doo
I told an off color joke at the party and the wife gave me the "Mom Look"

Hey dude, I think you better calm down, your girlfriend is giving you that "Mom Look"
