"Keep your head on a swivel" means to be constantly alert and aware of your surroundings, implying that one should be looking around frequently to observe potential dangers or unexpected events. It suggests a state of heightened vigilance and awareness.
The phrase likely originated from the physical act of turning one's head quickly and repeatedly, as if it were mounted on a swivel.
Other ways to express the same idea include "keep an eye out," "be watchful," or "stay alert".
Example:
"When you're walking through a crowded market, it's a good idea to keep your head on a swivel and watch out for pickpockets."
