A Brisbane man who captured video of an "unfortunate conversation" at a suburban bus stop wanted to remain calm when confronted by a woman who he described as a "little bit racist".

Jerome Forbes, 19, said he walked up to the Mount Gravatt Plaza bus stop, in Brisbane's south-east, where the older lady was sitting when he tried to strike up conversation on Monday.

"We were waiting for the same bus so I tried to create conversation with her to see how her day was or see what she was up to," Mr Forbes said.

"She sort of smirked at me in a way and it got me wondering why she would look at me like that, so I was just trying to be friendly to her."
