A video posted to Twitter by his classmate, Tatianna Ramirez, shows the memorable moment from the graduation ceremony at Warren Township High School in Gurnee, Illinois.
Mr Turcios walks past rows of his seated classmates after accepting his diploma. He briefly stops to talk to someone and suddenly attempts a backflip. But then, a faceplant.

He appears unhurt as he rolls over and begins to get back up to his feet.
Since being posted on Twitter on May 22, the 10-second clip has been 'liked' over 68,000 times and retweeted over 28,000 times.
Here's the moment from another angle:
"I was walking down the aisle, my friend was like 'Do a backflip,'" Mr Turcios tells WLS-TV.
"I was just expecting something wild to come out of it. I didn't expect it to be this big or for him to fail like that," says his friend Ms Ramirez.
Mr Turcios confirms while he wasn't physically hurt, he is basking in the glory of becoming a social media sensation.
