Amy: Oh my god!
Gwendolyn: Emergency PTA meeting today at 5:00. Will we see you there?
Amy: I'll totally get a sitter on a Tuesday night.
Gwendolyn: Yes, you can. You actually can.
...
Gwendolyn: I called this emergency PTA meeting to address an issue that affects the safety of our children. 
Vicky: Terrorism!
Gwendolyn: The bake sale: No BPA, no MSG, no BHA, no BHT, no sesame, no soy, and, of course, no nuts or eggs or milk or butter or salt or sugar or wheat.
Amy: No
Gwendolyn: What's that now?
Amy: I'm so tired of trying to be this perfect mom. I'm done.

At the end of her patience, Amy stands up to PTA head Gwendolyn at an emergency meeting about an upcoming bake sale. Amy is done trying to be perfect and calls out those who push her to perfection. This Bad Moms movie quote speaks to almost all parents.
