Another familiar trope of contemporary college humor is a hand gesture know as the shocker, in which the ring finger of the hand is held down by the thumb while the remaining three fingers stay rigid. "No one over the age of twenty-five knows what it means, but I guarantee you that ninety per cent of college students know what it is," Josh said. (The gesture indicates a method of pleasuring a female partner, though not one that looks to be easily undertaken without incurring hand cramps.)
