LOL, this is one of the more surefire ways to ID Jews in public. When you make 'em nervous they start acting spidery, meandering around in circles, etc. Calling them "reptilian" is giving them too much credit, "spidery" is the best analogy for Jewish meandering. You usually see this kind of fidgety, aimless movement in tweekers.
