Reports described Brexit pundits (supporters of the ‘leave’ campaign) so convinced ‘the authorities’ would rig the vote that they extolled people not to use pencils provided in the voting booths, because ‘the authorities’ could rub the pencil marks out and change the vote. Instead, they pleaded that voters bring their own pens to make their votes indelible. Of course this led to an inevitable social media campaign in which the Twitter machine lit up and promoted the racy hashtag #penisbetter.
