"I think that's more Davey who likes to have a chat," the 34-year-old said yesterday, two days out from the start of the three-test series in Centurion.
"You have to have a laugh about these things. I know if any of the Australians have a word, it's all in good spirit.
"Whatever happens on the park, you leave it on the park, and hopefully we can have a drink after and laugh about it."
ICC match referee David Boon fined Peterson 50 per cent of his match fee last year for his role in a push and shove with Pakistan's Adnan Akmal.
But Warner's character assessment of Peterson would be shaped predominantly by the one test they played against each other, at the Waca where South Africa clinched a 1-0 series win in 2012.
Peterson, who celebrated with much effervescence and snared match figures of 6-171 when the two sides last met in Perth, was unconcerned about how vocal he is on the field.
"I like to encourage my teammates all the time, and if that rubs the opposition up the wrong way then so be it," said Peterson, who has played 14 tests in a career that started in 2003.
"Whether they see it as a chip on my shoulder, that's probably their issue.
"I just try and enjoy my cricket, play it hard."
