Graduating High School is a big deal. You spend four years studying hard to gain the knowledge and tools you need to move on to the next phase of your life. So it's only natural to dance with joy when graduation day finally arrives -- or in this case "Shake It Off."

The valedictorian of Portsmouth High School in Portsmouth, New Hampshire -- Colin Yost -- decided to not only give an awesome speech, but he led his entire graduating class of over 230 students in a glorious flash mob as they danced to Taylor Swift's "Shake It Off." And it was AWESOME. 

Needless to say, everyone LOVED it.
