"Shounen" literally means boy in Japanese, but in otaku parlance often refers to Japan's biggest manga demographic: pre-teen and teenage boys. The world's most popular anime and manga franchises are usually shounen series, such as Dragon Ball Z, Bleach, Naruto, One Piece, InuYasha, and Death Note. These series usually involve some kind of ongoing battle or regular battles, usually of the fighting type (as in DBZ, Bleach) but sometimes sports-related (Eyeshield 21, Prince of Tennis) or intellectual (Death Note, Hikaru no Go).
