Over recent months people have begun chanting "Oh Jeremy Corbyn" to the tune of "Seven Nation Army" by the White Stripes in a display of support for the Labour leader.
After the election result two weeks ago, the chant has become even more ubiquitous, being heard at nightclubs...
Concerts...
And sport matches.
And now the chant has even spread across Glastonbury. Last night, thousands of people began singing "Oh Jeremy Corbyn" during a pause in Radiohead's set.
And people were proud.
Some were also found it strangely emotional.
But this wasn't the only instance of the chant being sung at Glastonbury. It broke out during a silent disco, too.
And people were also chanting on a buggy being driven around the festival.
