Answer: True
Slang is a type of informal speech that arises in particular "in-groups" in order to establish group identity and exclude outsiders. Slang is usually associated with young people and with urban environments, but this is not necessarily the case. Slang is not only dependent on group, it is also regionally based. Therefore, people from different regions or different countries will use different slang, even if they speak the same language and belong to similar age groups and social classes.
