That moment when you go to the store only needing a few things, then end up leaving with a whole cart of stuff, typically not including the original item(s) you came for. This term is not exclusive to Costco and can be used for any store that manages to get you to fall into its consumerist trap.
"Dang, look at all this stuff we bought. I only needed a couple of things !"

The feeling you get when you’ve already picked up everything you need from Costco but continue shopping and your bill is three times what you expected.
The feeling you get when you unload your car after a Costco run and you hope noone sees the excessive amount of bulk merchandise you’ve purchased for a family of two.

She felt the weight of Costco shame set in as she put her massive pack of lemons,
She felt an immense amount of Costco shame as she unloaded her box of 120 ice cream sandwiches for a family of two from her car as the hot neighbor walked by.

A costco gorge is when you go to Costco to by your shit and everywhere you turn there are hoards of cheap ass motherfuckers blocking your way to get free samples of cheese dip and pizza nuggets.
Tasha went to Costco to buy her veggies and tampons. It took her so long because every aisle was over run with old people and turban wearing Indians Costco gorging. She almost got trampled by three old ladies.

I went in to Costco with 5 items on my list. I walked out with 15 items and spend $200 more than I should have spent after Costco whispered to me - buy me!

Coscto Privilege is like White Privilege but it involves people who back up traffic at a Costco Parking lot in order to save walking 10 extra feet. People who exercise this privilege, instead of getting a bit more actual exercise by walking a few feet, usually drive large SUV's with "My Kid's an Honor Student" bumper stickers.
Dammit, you see that soccer mom in her SUV. There's 10 cars behind her that have to wait because of her Costco Privilege.
