Yup, Boss Man is right, body builders usually eat mass amounts of calories with the idea of gaining as much mass as possible, followed later by a cutting phase to get lean. The idea is that it is virtually impossible to lose fat and gain muscle at the same time. This sensibility is not entirely accurate though, particularly if you are new to resistance training. Over the years I have seen many of my clients gain significant muscle while leaning out, though not to body builder levels.
