Yorktown High School in New York is closing its school year with some serious dance moves. Last Thursday (June 11), three juniors -- Josh Grant, Taizhier Green and Kevin Carroll -- showed off their chops in the cafeteria with a dance-off that might as well qualify them for "America's Best Dance Crew." Videos of their breakdancing hit the internet and have since gone viral.

MTV News spoke to Grant and Carroll, both 17, about their newfound fame and how it all went down. Check 'em out in action below. Grant's wearing the white t-shirt, and Carroll's in the black shirt.

"We went to the lunchroom and then we started clapping," Grant told us. "We wanted somebody else to hop in [because] it was just [Green and I] dancing the whole time so no one else wanted to hop in -- I guess they were shy -- but then I knew one person that would ... so I called out Kevin [Carroll]."

Grant, who grew up dancing in formal groups as well as casually, is no stranger to lunchroom dance breaks. He had already performed in the same cafeteria a week earlier to say goodbye to the school's seniors, who ended school a few days before underclassmen did.

The last day of classes for the entire school was a half-day, and many of the students finished cleaning out their lockers early and had some time to kill.

Grant, Green and Carroll kill it so hard in the videos that it may seem like the trio are best bros. Turns out, they mostly just pass each other in the hallway -- but happen to share the same passion for dancing. "I don't really know Josh or Taizhier that well... I mean, I've talked to them in the halls a little bit before, but I'm not really close with them," Carroll told us.

Carroll is also an experienced dancer who will begin choreographing next year; he performs with the Country Academy of Dance and Yorktown High School's dance company. Grant and Green found out about his mad dancing skills and vice versa thanks in part to the King of Pop.

"I remember once Josh and Taizhier asked me to dance in the halls," Carroll said. "The thing is, I carry a speaker around in the school. ... One day I was playing Michael Jackson and [when] I passed them, they asked me to dance and I did. We had a tiny dance-off but no one was around at the time."

People were certainly around for their next friendly competition. Carroll had been waiting by the school's writing center for a college essay workshop, then he heard talk of a flash mob happening.

"I got really giddy at that only because I love flash mobs," Carroll said. "I looked over at the cafeteria and saw this huge crowd of people and thought, oh, they're watching a flash mob, I want to go. ... I ran right over. ... It was [Grant and Green] dancing a little bit, and they see me, and they drag me in. Next thing I know everybody's chanting, 'Kevin! Kevin! Kevin!' Then we started dancing."

A crowd of cheering students surrounded them -- school administrators and teachers were cool with it, too -- and videos of their moves hit every social media platform out there.

"I wasn't expecting it to go as viral as it did. When I left school 20 minutes after [the dance-off] my whole Instagram, my whole phone [was] blowing up. ... It's kind of surprising," Grant said.

But becoming a viral internet star has led Carroll to question the effect that sudden fame has on people.

"There are people in my school now who I have never spoken to, some of whom I have never even seen that suddenly want to be my best friend," he said. "Did I need to be famous for you to want to be my friend? It just seems kind of weird, because it kind of just shows what those people value."

Carroll also explained that he thinks many media outlets have "badly handled" the reporting surrounding the videos.

"I was looking at all the headlines and they say like 'nerdy kid shocks crowd' or 'did not see this coming' ... stuff like that," Carroll said. "It's kind of pointing to the race issue of it a little bit, and the thing is ... would it have made a difference if either one of us were Asian or Latino or anything? ... I just see so many people, they think 'the white kid with glasses...' The assumption is they can't dance. But no, that's a wrong assumption. I like how [the video] proves that wrong ... I think that's maybe why it's found so much traction -- it breaks the stereotype."

As for the nerd/geek label, Carroll said it's "fairly accurate" since he takes advanced courses and is really into scientific research. He spent six months designing a national survey for parents of children with autism, and he broke records when the questionnaire got a whopping 1,400 responses. Local news stations covered this achievement, he said, but he never made national news -- until now.

"I do one dance for less than five minutes in my school cafeteria in one day, and I get recognized nationally for that," Carroll laughed. "Go figure. Life is so weird."
