Using "like" often in a sentence is more for young people from the Western part of the country. It stems from the Sweet Valley High series of books that came out in the early 80's. Which was a book series about High School girls in Calf. I was a young teenager and read every book in the series of course. As a teenager, I also picked up the habit but only for a year or two when the series was cool. Anyway, you don't hear it much in this part of the US or with older people.
