costco try 

The act of buying something you might not need from Costco because you can always return it later. Similar to a college try.

There was a really cool air fryer on sale, so I gave 'er the ol' costco try.

Costco Whisper

Items not on your list, but Costco items "whisper" to you "but me" or "you need me".

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!

Costco intellectual

A person who usually lives in a safe, liberal bubble who believes you can run the world as if it's a club designed to keep out poor people. They generally take edge case, nuanced scenarios, or things that can only be done in high trust systems and try to apply them to every situation.

Have you seen her instagram stories? She's such a Costco intellectual.

costco guys 

People who soullessly walk around costco with nothing behind their majestic eyes, and eat chicken baked and a double chunk chocolate cookie.

Hey look at those costco guys right there with their chicken bake.

Costco shame

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.
