A group of soccer moms who can talk about nothing besides their kids, their kid's teacher, their kid's father, their kid's diaper rash, their kid's schedule. They are also fiercely competitive over who is the best mother and whose kid is the best. They are usually white, wealthy, suburban, and BORING! They can also be catty, bitchy, passive-aggressive, and BORING!
Lines you will hear between members of the mommy mafia:
Pat - "Katie is the smartest in her class."
Sue - "Well Timmy was voted most popular by his teacher."
Jan - "Bob just got a promotion so I'm taking the kids to Disney."
ME - "You're all BORING! What am I doing here?"
