: In Vermont I've heard the rare expression, "they/he/she wouldn't/don't know enough to pound sand into a rat hole."
: Anyone else hear this one or know what the origin could be?
It seems likely that this is one of several euphemistic versions of what seems to be the original form, "Go pound sand up your ass." On the other hand, it may be that the latter form is an intensified and vulgarized form of some other original. See:
