The act of manning the helm of a vessel (usually while inebriated or consuming a beverage of some sort) while it is being towed on a trailer behind a truck. Most commonly road boating is seen in MD when the truck bed is full of people and golf bags and space and time are of the essence. It also reduces the number of DDs needed for a large group of people.
We had a couple guys roadboating to the golf course because the truck was full and they wanted to drink on the ride there legally (drinking on boats while they move is legal unlike trucks).
One who travels with a backpack and moves place to place eating out of trash cans. Also picking at people's curbside leftovers, sleeps in abandon buildings , never showers, nappy hair, smells really bad. A favorite of the roadrat is piles of 2nd hand clothing that is not washed and preferably pissed stained rags. Also is an extreme hoarder. Usually can be seen in the company of a hoodrat, whorebag, and a dopefiend always pushing there favorite form of transportation a shopping cart.
