clustermers 

A small crowd of people who enter a store as a group.

Having clustermers come in can be a store-owner's dream-come-true if each of the members of the group buys a few items, but it can also be a nightmare if they all just want to use the restrooms.

Clustermer 

When a customer or client doesn't have their act together, thereby creating a headache and more work for you.

You just made a big sale, why are you all bitter?

The time I spent getting him to finally figure out what he wanted was ridiculous. That clustermer was way more trouble than he was worth.

clusterfest 

A complete and total shitshow of a failure that still somehow benefits the rich and powerful.

Thanks to the manufacturing and shipping clusterfest, lumber prices are out of control.
