Big Money Bertha:
That parent who seems to think that all other parents are made of money. You have no idea how Big Money pays her bills because she seems to spend all her money on cheerleading. The fact that Big Money Bertha spends all of her money on cheer would not affect you, except for when Big Money Bertha is Team Mom/Team Parent/etc.
When it is time to do things like chip in for team gifts, Big Money Bertha suggests that you all contribute $75, because anything less would be uncivilized. When you suggest homemade picture frames for graduating seniors, Big Money says let's go all out and suggests a $150 monogrammed tote for each kid.
