A product, or person advertised by the disney corparation. Often talentless, bad actors, bad singers. Some of them are whores ( Miley Cyrus) some are bimbos (Jonas brothers) They usually attract large amounts of pre-adolecent girls, and sometimes boys. Not to be trusted. Or liked.
when all teenage disney stars feel the need to become stupid sluts and eventually leave the show/channel to pursue carreers in prostitution, being whores, etc.
when someone is a star of a disney channel show they are always on like at least 2 other ones as well. Disney channel is too cheap to hire more actors, so they use all the same ones and make stale repetative shows.
