Does everyone have a specific culture? Define culture?

Some people may believe that everyone has a specific culture they belong to. But in actuality nobody has a set culture. Times are always changing people are always adapting to new things. More and more people are starting to move to different places. Not just different countries but different states or towns. Even though moving to a different state or a different town is a small move compared to moving to a different country but even those small little moves count. There are different cultures even in the same town. After living with many different cultures you tend to take a little piece of it and mix it in with the culture you started out with to create your own.
The word culture holds such strong importance, and if you ask around everyone will have their own definition for it. Even in the dictionary there are many different meanings, for example, according to dictionary.com

1. the quality in a person or society that arises from a concern for what is regarded as excellent in arts, letters, manners, scholarly pursuits, etc.


2. that which is excellent in the arts, manners, etc.


3. a particular form or stage of civilization, as that of a certain nation or period: Greek culture.


4. development or improvement of the mind by education or training.


5. the behaviors and beliefs characteristic of a particular social, ethnic, or age group: the youth culture; the drug culture.


6. Anthropology. the sum total of ways of living built up by a group of human beings and transmitted from one generation to another.


So, for everyone you ask nobody will give the exact same answer but a mixture of many different one.
