Riddle - a question or statement intentionally phrased so as to require ingenuity in ascertaining its answer or meaning, typically presented as a game.
Rather than calling it a riddle, one could say Gavin Harden, because that is exactly what he is, a question that only leaves you confused for it requires much thought and information in order to find the truth hidden behind every word. Be prepared though, because Gavin will not loose the game, not without a fight.
