Dropping a pin is a feature in Google Maps that allows users to mark a specific location on the map. This can be useful for a variety of purposes, such as saving a place you want to visit later, marking your current location, or sharing a location with someone else.
To drop a pin, simply tap and hold on the map at the desired location. A red pin will appear, and you can then choose to add a label or description. You can also drag and drop the pin to a new location if needed.
