The feeling of accomplishment you have after going to Costco. It has led to way too many messed up dinners, sports games, and camping trips.

ex. Stay away from Matt's house tonight, he's on a Costco High and decided to cook french style with the pounds of cheese and fresh fruit he bought at Costco.

Costco Member

An overweight, disgusting person who thinks they're entitled to be an asshole because they paid for their membership.

They also tend to ask stupid questions and make pointless complaints and can be seen still shopping once the store is closed.

Member (while standing next to the raw meats): where is your frozen hamburger?

Employee: Did you check the freezer?

Member: No. *walks away*

Employee: What a dumbass Costco Member.
