bampot /BAM-pot/. noun. An idiot; a fool; an obnoxious person. Scottish slang of unknown origin, probably related to Northern English barmpot (a container for storing yeast) and barm (the froth on fermenting malt liquor; the head of a beer) both also used as slang with the same meaning and from which we also get barmy, slang for being mentally unsound.
