To "teeter" means to move, balance, or wobble unsteadily. It is often used to describe a back and forth "swaying" motion to balance on something, like the train mentioned in this video. Ex: She was not good at walking in high heels, so she teetered back and forth. Ex: The bridge suddenly collapsed, and many cars teetered dangerously on the edge.
