CRUMBHUNTING 

The act of emptying all of the bags of chip crumbs from your pantry into a zip lock bag. Start hunting.

I had so many bags of chips with just crumbs so I put them all in a zip lock bag and I went CRUMBHUNTING for different flavors.

Crumbhunting 

Emptying all of the bags of chips with just crumbs in them into a ziploc bag. You never know what flavor you will find on the hunt.

I was crumbhunting and finally found the Doritos crumbs.
