Francisco Valdez Mendoza expressed very well the meaning of 'Móndrigo' in México. Very precise definition. Just lets say that is a soft -a kind of euphemism, for: Abominable, bellaco, unworthy, infamous, petty, miserable, crook, vile scoundrel guttersnipes, ruin. It is frecuently used in a friendly manner to express some action that could be questionable but at the end we think it is funny.
