Cách sử dụng
The expression "number one" is commonly used to refer to oneself or the most important thing or person in a particular situation. For example, if someone says "I need to go to the bathroom, number one," they mean they need to urinate. Similarly, if someone says "My family is my number one priority," they mean their family is the most important thing to them. It's important to note that this expression is very informal and should only be used in casual settings among friends or family, not in formal or professional situations.
