Rude, rough, or uncouth people who lack manners and consideration.
From Old Norse 'lúti,' meaning 'to stoop' or 'to lurk.' The sense evolved to describe someone who lurks or lurches about clumsily, eventually meaning an uncouth or rude person.
The word 'lout' has been used to describe uncouth people since medieval times, showing that people have always been frustrated with those who lack basic courtesy! It's interesting that the word originally described physical clumsiness, then evolved to mean social clumsiness.
