A frog's well is a common form of argument and is an informal fallacy. It's a common fallacy, where a broad generalized claim is made on the pretext of a small geographical area, ignoring the rest of the globe. One who engages in this fallacy is said to be "digging frog's well".
Statements like, "You know what! Sanskrit is the mother of all languages." are considered frog's well fallacy. The one who is making this kind of fallacious arguments, is digging frog's well.
