yo

Everyone knows about the concepts of when "yo" is used, in this concept, it is the simple greeting, except with much more swag (something "we" asians got). Although "yo" has been used a lot more frequently by your average gweilo, persons don't know where it has originated from. The term "yo" actually came from the word: "anneyeonghaseyo". "Anneyeonghaseyo" is korean for hello, in a formal matter. Note the last 2 letters, yo. Neti's got sick of such a long-ass greeting, and moved on to a more shorter greeting: "yo". Because koreans are either so cool (male) or so cute (female), their slang was passed on to the people of today.
