Getting down on one knee, curling one's wrist to one's chin, and looking up, mimicking the pose of Auguste Rodin's classic sculpture "The Thinker".

In response to the fundamentalist craze of Tebowing, American Atheists President Dave Silverman has come up with an atheist version called "Thinkering."
Someone commented that the pose looked too similar to Tebowing, to which Silverman responded: "That's the point. The difference is we don't bow our heads in blind submission, rather we consider and conclude for ourselves."
A portmanteau of "thinking" and "tinkering". Means to think about something by tinkering with objects relating to the problem under consideration. Usually unguided, exploratory and individual, often a very good way to explore aspects of difficult problems or to find solutions where none are obvious. In other words, an active form of thinking.
Akin to solving a puzzle (like a rubiks cube) by trying to solve it rather than just sitting and staring at it.
