Verb. To perform a horse trailer you need a truck with a rollbar, a horse trailer behind said truck, a friend to drive the truck, and obviously some nasty ho. What will be done is the ho is tied to the rollbar of the truck, with you pounding the bitch from behind, your friend drives the truck and trailer down the road, while the girl whinnies like a horse.

Walking around with your dick tucked into your waistband. This is one of the most popular methods for hiding an unwanted boner in public. It's called trailer hitching because if your dick tip pokes out the top of your pants, it looks sort of like a trailer hitch.
"I popped a boner in trig class. Nobody knew though cuz I was trailer hitching like a motherfucker."

When Maryann saw the black velvet painting of Elvis, Princess Diana, and Dale Earnhardt drinking beers while floating on clouds in heaven, she just couldn’t pass it up. It was just TOO great a Trailer Treasure to not buy.
