Running for exercise and picking up trash you find along the way. It's good for the body, mind, soul, and environment! Started in Sweden but is making its way to the U. S.

A combination of the word Thanks and Wanker.
Can be used when talking to your boss or somebody else who seems to be getting on your nerves.
