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.
That Lollyringer really fooled me, it sure didn't seem like he had that outstanding performance in him. He freaking won that competition single handedly after looking like a complete slacker.
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
