A York Regional Police officer surprised the crowd at a car meet Thursday evening when she delivered a freestyle rap.

"I like my donut frosted cream and my coffee double double, I'm trying to drink it hot before someone starts trouble," Const. Amy Oliver rapped to roars of approval from the crowd.

Oliver had been invited to the stage after organizers at the Strada car meet, located in Vaughan, Ont., found out she rapped as a hobby.

Her freestyle also contained a plea for haters to "take a chill pill" and for people to feel comfortable bringing problems to her:

"I 100 per cent agree in love and equality, I want everyone to feel free and feel like they can come to me, without saying police don't care."

Oliver said the response to her video debut has been "overwhelming" and very unexpected.

'It's just something I've always done'

"Ever since I was younger, I've enjoyed rapping, I've enjoyed freestyling … it's just something I've always done," she told CBC Toronto.

Oliver said she didn't intend to perform on Thursday, but when everyone started chanting "YRP" — for York Regional Police — she took the stage.

"I didn't realize how viral it would go," she said.

Oliver was on "paid duty" Thursday evening, meaning she was there to provide security.

"She was just trying to build relationships with the group that are there," York Regional Police spokesperson Const. Andy Pattenden explained.

"In her free time, she does freestyle rapping. So this rap battle began," he said.

The rest was captured in a video posted to Twitter, and is now internet history.
