A lollygagger in disguise. Actually a very skilled, quick, talented, witty individual that is posing as a lollygagger as to "sandbag" in order to not alert opponents or an adversary of ones actual prowess. To fly under the radar as a lollygagger but when the opportunity arises take advantage of the moment to exercise this dominance.
