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:
It could be used as a condensation of murderer and imposter, having the same uses as both simultaneously would entail: You murdoster! You not only killed someone in cold blood, but you also impersonated someone to cover your tracks.
A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
In use:
Shackteâu - We thought it was an abandoned shed until the realtor called it a rare alpine Shackteâu with unobstructed views and listed it for $2million.
