when you are riding in the front seat of you're moms car and she has to hit the brakes or do some crazy manuver to avoid something, then she stretches her arm across your chest holding you in your seat as if she was going to save your life.

Get the mom bar mug.
Similar to a soccer mom, a bar mom is a white middle or upper-middle class woman in her mid-40's to mid-60's who sees her adult children only in bars. During free time she is found at the bar drinking, playing pool, playing darts, or playing poker. A bar mom is the equivalent of a bar rat, but with children.
Did you see Vanessa at the bar Tuesday night?
Yeah she is such a bar mom.
