slang A mother who tends to overcommit herself and act with a perfectionistic intensity. Often perceived as trying or being able to "do it all." I don't know how those Alpha moms do it. At some point, you just have to surrender to the chaos that is parenthood, or else you'll go mad. If you're an Alpha mom like me, you're probably secretly exhausted from taking part in every activity that could possibly involve our children.
