What is spanish slang?

Question

"Spanish Slang" was something that was read inside of a book and is spoken throughout

Answer 1

Slang, in any language, is made up of words that aren't really "correct" or "proper" but are accepted by many people. For example, the word "homeboy" is not an actual word, but it is slang, meaning at least some groups of people use and understand it.

Spanish has uncountable slang words, just like English, if not more!
