Periphrasis (per-if’-ra-sis): The substitution of a descriptive word or phrase for a proper name (a species of circumlocution); or, conversely, the use of a proper name as a shorthand to stand for qualities associated with it. (Circumlocutions are rhetorically useful as euphemisms, as a method of amplification, or to hint at something without stating it.)
Here comes Big Mac doing the Big Trump walk and talking incoherent talk–very cheesy.
