What are examples of boondoggling?

There are 3 meanings for the word 'boondoggling'. 1. An unnecessary or wasteful project or activity. 2 a.A braided leather cord worn as a decoration especially by Boy Scouts. b. A cord of braided leather, fabric, or plastic strips made by a child as a project to keep busy.

Below is a link for meaning no. 2, but i presume you are asking about meaning no.1. So an example for that is playing handphone games to kill time.

Hope this helps :)
