If we're totally honest, we don't know an awful lot about this video.
We've no idea who the linesman is, or indeed where the footage was shot.
We're therefore very grateful to Roma's Belgian midfielder Radja Nainggolan, whose tweet alerted us to it.
With the ball up the far end of the field, the linesman finds himself standing just shy of halfway immediately in front of a raucous bunch of supporters.
As the crowd chant, the linesman's head begins to nod in time to their song. Sensing the fans' approval, he goes one stage further and breaks into a full on dance.
