U Know Fan Service..??

Fan service (ファンサービス, fan sābisu?), fanservice, service cut (サービスカット, sābisu katto?), or simply service (サービス, sābisu?), is a vaguely-defined term primarily used for Japanese anime and manga to refer to elements that are unnecessary to the storyline. There is a widespread belief that fan service is only material that is designed to amuse or excite the audience with sexually-derived content, but the term can be applied generally to any nontopical content that is added solely to please fans. When such content fits within the storyline it would not usually be considered fan service, but excessive content is usually considered gratuitous regardless of its justification.

While the term is used primarily with respect to Japanese animation, any gratuitous content within entertainment may be considered to be fan service. The term is also occasionally used in the video gaming community, for example. The meaning remains mostly the same — content added for the sake of fans and not for any actual gaming value.
