Schiested means: This refers to someone being victim of someone who intentionally and willfully swindles, grifts or takes advantage of you in some way, but always in an unfair fashion. You have been sexed by someone who isn’t interested in you. The loss of property or money, as well as the dismay at being taken advantage of by others can be devastating for those who have been schiested. Many people who are schiested don’t report it because they feel ashamed or embarrassed. This makes it one of today’s most overlooked problems. (in Community Dictionary, added by Cayetano Crespo)
