the body's involuntary confession that something just outsmarted your seriousness.
means Producing the spontaneous sounds and movements—the chuckles, giggles, or guffaws—that erupt when something strikes you as funny or joyful.
from From Old English 'hlæhhan' (to laugh), tracing back to a Proto-Germanic root 'hlahjan'—a cousin of German 'lachen' and Dutch 'lachen.' The whole family is thought to be echoic, born by imitating the actual sound of the act: that breathy 'hah-hah' rendered into letters. The silent 'gh' in our spelling is a fossil of the old guttural 'hh' sound, once truly pronounced before English quietly swallowed it.
