Gotgot i deffe'.
A toothless person is loose-lipped.
Someone who is gotgot says more than s/he should. S/he can't keep secrets. The gotgot person is very free with his or her information. S/he will tell on you and get you in trouble. Gotgot people make good informants.
But why should someone missing a tooth, someone doffe', be necessarily gotgot?
The reasoning of the elders is :
"Yanggen guaha fåtta gi kellat, man malågo ha' siempre todo i ga'ga'."
"If there is an opening in the fence, all the animals will surely run off."
Therefore, if there is an opening in the teeth, words will surely escape!
