Truminator (tru-min-a-tor), noun. A numpty. Originally conceived as a derivative of Shermanator (proliferated by the eponymous character in the American Pie series of films), this denotes a single, white male of similar characteristics (i.e. ginger, sexually inadequate, prone to self aggrandisement and delusional self-belief) who has the surname Truman rather than the original Sherman. Also known to be fond of "pressing the button" in the hope of achieving "judgment day".
Here comes the Trumanator, he's a sophisticated robot sent back through time to change the future of one lucky lady... but sadly not so sophisticated that he can spend much time in direct sunlight... (as a result, Trumanators usually operate during the hours of darkness)
