I could't find this expression out of google.

Sometimes they use their own make up words to express what they wanted to say.

In my daily life, I have quite a few chances to learn different kinds of English. One of my English teachers is from Great Britain and he likes to teach us different kinds of phrases and expressions used back in his country.Some of my friends are Canadians and some of my classmates are from the U.S.and some of my co-workers are from India. And of course I have some friends from everywhere of China, and sometimes they teach me different kind of dialects, just for fun.  @_@.
