AlphaTauri's Yuki Tsunoda has explained where he picked up the habit of swearing so much, as the Japanese rookie has picked up a reputation for having broad vocabulary of bad words in his repertoire.
Tsunoda's team radio so far this year has revealed that he may be mild-mannered away from the cockpit, but his fiery temper takes over when he's out on track.
As a result, Tsunoda has explained that a lot of his English swear word knowledge has come from hanging out with Carlin mechanics in the junior categories.
"I like bad words!" Tsunoda told Tom Clarkson on the Beyond the Grid podcast.
"So, I had a really good relationship with the Carlin mechanics also with the engineers, sometimes using bad words. And I learned from there and just I was using bad words for [the] job, you know, and also having fun and I think that's suited well for that job.
"But yeah, as soon as I realised it when I came to Europe, I just started not really using the bad words because I was using too much bad words."
Asked whether he represents the average Japanese person by swearing so much in English, or whether he's even aware of how much he's swearing in a language that's not native to him, Tsunoda explained that he knows he's an outlier.
"Japanese don't swear much, I think most of Japanese won't swear much," he said.
"Yeah, they're quite respectful. I think I'm ruining the Japanese image!
"So I'm breaking the Japanese way. So I'm not good at that. Same age as me, the same generation as me, they swear a lot or with friends but, with older people, they don't swear much."
