What's your definition of casual dating?

Everyone seems to have a different definition for the term "casual dating". Is this similar to being a friends with benefits? 
The reason I asked is because the guy whom I've been going out on dates with says that he's interested in casually dating. He also said that he enjoys talking to me and spending time with me and would like to see where it goes. He recently just got out of a relationship so I completely understand not being in a rush to jump into another one.  But I'm still confused about what that means in terms of us.
