Giggle (g hard).

Have you found a giggle’s nest? A question asked in Norfolk when anyone laughs immoderately and senselessly. The meaning is, “Have you found a nest of romping girls that you laugh so?” Giglet is still in common use in the West of England for a giddy, romping, Tom-boy girl, and in Salop a flighty person is called a “giggle.” (See Gape’s-nest.)
