The East Midlands Today reporter said she was "genuinely shocked" by what the man said.
She said: "It's not banter, it's not funny and no-one should have to put up with it."
The TV presenter said it was good people were now talking about the issue but said claims the video was staged were "absolute nonsense".
She said: "It's fairly obvious from my reaction that it wasn't staged.
"If it is a craze it doesn't make it any less offensive."
