Gigantic British Moon at Trump on his State visit

Let's give Trump the only welcome his State visit deserves with a great British tradition. He can wave at our arses and only our arses as he fulfils his dream of riding down The Mall in the golden State carriage. It's been too long, people. Now is the moment for a collective national moon. Date to be announced!
