obnoxious minority
A small group of people who clog up the whole conversation with their nonsense. They’re not smart, but they think they’re the best.
‘They’re like the loudest people in the room who think they’re the only ones who matter.’
‘They’re just a few people who like to argue about everything, even when it doesn’t matter.’
‘They’re not even right, but they’re always the ones who shout the loudest.’
