This came out kind of funny. 'Simantikos' is where we get words like 'semantic'; it's the property of signifying, like "the signifier" in linguistics. 'Simantikos allos' makes me think of the Signifying Monkey in American folklore, only it would be The Signifying (An)Other, which sounds like a really labourious grad thesis.
