The act of writing TATE (all caps necessary, or it doesn't count) in random places all over any object. It is unclear who started TATE-ing, but now, you can't possibly name everyone who does it. TATE does not stand for anything, but is found everywhere. TATE is an actual name, but i will not give his last name for privacy matters.
