Today’s word of the day, boia, traditionally means an executioner or a hangman. Colloquially, it means nothing of the sort.
One uses boia to express abundance, usually to refer to either very cold or very hot weather. However it can also be used to say great … anything.
‘Fa un caldo boia a Roma.’ – It’s super hot in Rome.
‘Questo mal di gola mi fa un male boia!’ – This sore throat hurts like hell.
