Pleasure boatin' is the act of sitting on one's boat; except, instead of physically traveling anywhere on the boat, the boat is free to float aimlessly around its present body of water. Although nicer boats are always preferred for this activity, pleasure boatin' can take place on anything from a raft or inner tube to a yacht. Pleasure boatin' is also strongly associated with the activities of day drinking (especially whiskey and beer) and is a popular hobby of Midwesterns living on the Great Lakes.
Visitor: "Why isn't that boat going anywhere? Those people have been sitting on it drinking ALL DAY."
Knowledgeable Midwesterner: "Oh, they're just Pleasure Boatin'."
