A portmanteau of both murderer and imposter, where someone has not only been proven to have murdered someone in some way, but also having taken on someone else's life, appearance, and ego. Both deeds don't have to be related to each other in order for a person to be a murdoster.
An example of this word being used in a sentence are as follows:
