Katy Perry inspired many teens to 'Roar' in 2013
The trend seemed to take off after the pop star and "Good Morning America" announced the "Roar with Katy Perry" video contest.
Soon after, several lip-dub videos hit the web and went viral on YouTube. To go along with the song's theme, many of the clips featured inspiring stories from youngsters around the county.
Among them was a video created by students from Verrado High School in Buckeye, Ariz. that featured a group of teens who helped a special needs classmate make the cheerleading team.
Most recently, PEOPLE featured an uplifting "Roar" video created by a Canadian high school group who rallied behind a classmate recently diagnosed with cancer.
We can't find one "Roar" lip-dub video we don't like, so we decided to showcase some of them below.
