The mom who is about to lose her sh*t on her kids.
As much as we love our sweet little kiddos, they can be a damn nightmare on shopping trips. And given the nature of Costco (read: stimulants everywhere with lots of space to run around), they tend to go a little nutty. You'll find this mom constantly hushing and giving her kids a hell of a lot of side-eye. A tell-tale sign she's about to officially lose it? The stem coming out of her ears.
