Slang (Jerga in Spanish) is what people use to name words in a different way that creates a deeper connection for a particular group of people. Slang makes part of any language and it is what people use to feel identified with a particular country, region or group. In some cases, the word could become so popular that people do not even realise that is a slang word. Of course, this type of language is very informal and it should only be used in speech rather than writing.
