When I really really really enjoy the first taste of  a dish, I sometimes spontaneously break into an odd little shoulder-jiggling dance accompanied by sounds of appreciation that I don't quite know how to spell. Sort of like - uhuhuhuh! Jiggle,jiggle, jiggle -uhuhuhuh. When I realized some time ago that I have this tendency I worked hard to control it - It's not very dignified to be making incoherent sounds of bliss when you are trying to be objective in your approach to evaluating your meal. Still every now and then I forget - the food is great- and the jiggle appears.
