A cocktail consisting of the remainder of your previous alcoholic beverage, mixed with water from the melted ice of that drink.

After I finished my old-fashioned on the rocks, I stayed to watch the end of the game and sip my meltini.

multividual 

multividual n Latin multus, many + Latin individuus, indivisible Ð a multiple individual that embraces many selves and in a technological perspective can possess multiple bodies.

As early as 1970s, psychologists indicated the emergence of a proteic type of personality who combines the properties of different individuals. This is not a schizophrenically split personality, but the one rich in roles and selves, a multividual who cannot be confined to a single self.

The multiplicity of selves often reveals itself in the acts of inspiration and artistic creativity. Eventually these multiple selves will acquire not only symbolical and imaginative embodiments, like in theater, but also independent bodies. Like a bio-species is exemplified by a multiplicity of individuals, a multividual will become a psycho-species exemplified by various organisms. Such multividuals will reach across continents assuming various material guises and performing various social and professional roles, and simultaneously they will be aware of their unique destiny and moral responsibility.
