VidCon is a conference held in California each year in which online videophiles (herein referred to as YouTubers) get together in the real life and discuss all things online video related.
One such individual in attendance was Irishman David Wogan who runs the YouTube channel PlayHurling. The channel is dedicated to 'teaching hurling to North Americans through video content' and while he was at VidCon, Wogan wrangled in some other YouTubers to see what they would be like with hurley in hand.
All in good fun but the Quidditch reference is certainly questionable.
