A filler is a guy/gal that you seemingly 'like' or have a 'crush' on. This person is made to fill in a feeling for a person that you really love but is not actually with you. It's for a lost sense of love- as if you need someone, anyone at all to love at all times.
Molly loves Bill.

Bill moves to New York.

Molly doesn't see Bill.

Molly's brain likes Tim. But Molly's heart loves Bill.

Tim is a filler. Molly needs someone to 'love'.

A term used by anime fans to refer to episodes or segments devoted to content irrelevant to the episodes that the filler is sandwiched in between. These are usually made to allow manga writers and illustrators to catch up with the work, to bridge gaps made by hiatuses, or to be put in place of chapters delayed to later parts of the series.

"Filler" refers to story in an Anime that was not in the Manga. These are created because Anime production usually outpaces the Manga. Fillers do not further the story and usually are of a lower quality both visually and narratively.
