High school graduations are typically a cause to celebrate, so Portsmouth High School's graduating class of 2015 felt cause to dance to Taylor Swift.

From the podium kickoff cue and boogie to the whole class dancing in their seats, and then out of them. This class knows how to 'Shake it Off!'

Other graduating classes have had similar flash mobs like Kahuku High School, in Oahu, Hawaii. The put on an impressive dance routine set to a long medley of songs and ended with “Kaipahua Kura,” war dance of the Maori people of New Zealand.
