zigzag

A zigzag path has sharp turns that go back and forth, like a winding road.

When people talk about zigzagging, they often mean moving quickly from one place to another with lots of changes in direction. Imagine you're on a bike ride: you're going fast but then you have to slow down for a turn, and as soon as you straighten out, you hit another curve. If someone says "I was driving zigzag through the streets," they probably mean their route was quite winding and unpredictable. The word can also refer to lines or patterns that go back and forth in this way – like stripes on a shirt.
