Definition
A polite way of telling a shop assistant that you are not yet ready to buy anything and do not require assistance at the moment; commonly used when browsing in a store.
"Hello, do you need any help?" "No, thank you, I'm just looking."
When the shop assistant asked if he needed help, he replied, "I'm just looking."
She smiled at the enthusiastic sales clerk and said, "I'm just looking, thanks."
