Trigger T.H.E. Human Equine
There’s an extended community of shoulder-riders and their mounts, usually female riders who are carried on the shoulders of male “horses” as a form of domination. In this video, Trigger the Human Equine, one of the most well-known members of the shoulder-riding community, carries a female rider while wearing a harness, saddle, bit, and fake tail.
Unfortunately, Trigger passed away in 2014, according to this elegiac post on the Ultimate Shoulder Riding forum. To quote shoulder-riding enthusiast checkmateguy, “Old ponies never die; they just gallop off to pastures new.”
