The process of putting your change into a vending machine and mashing every button to recieve an unexpected and usually disappointing item. It is however funner than just selecting an item.

If there are empty slots, thats just risky business. You have a chance of getting nothing!!!

The results of a vending machine random usually are a lot of swearing and anger. Strangely enough, you will find youself doing it again.
I pulled off a vending machine random a few minutes ago and i go salt & vinegar chips, what a waste!!
