As rain hit the Zandvoort race from the start, Norris begged his team to stop for intermediates. But McLaren was one of several squads, including Mercedes and Williams, to brave it out and wait for the short shower to pass.
As the circuit got wetter, Norris responded furiously to his race engineer's call to stay out, saying: "What the f***, are you stupid?"
Norris then overruled the call to stay out by pitting at the end of lap thee, by which time the damage was done and the Briton - who had started on the front row - had lost any podium chances.
Norris felt outbursts, such as he made in Zandvoort, made him "look like an idiot" but says he only realises afterwards that his radio messages don't always come across as intended.
"We just spoke about it a bit now," he said when asked by Autosport if he and the team had reviewed the exchanges.
"When you look at it after you always think 'I make myself look like an idiot' and I get that.
"But the people I speak to know that I would never mean something like that, of course.
