yachtism 

A pervasive developmental disorder of the financially well-to-do that inspires them to purchase a yacht (any long boat powered by a sail and a douche bag), a membership in a country club, any Ivy League or otherwise private education and the apparent permanent blockage of the anus with any member of the phylum Arthropoda.

That rich asshole with a boat is clearly suffering from a bad cause of Yachtism.

yachtsman 

A cocktail invented at Freddy's Bar (Brooklyn, NY), containg vodka, grapefuit-juice and soda.

"This yachtsman is so refreshing!" OR "This yachtsman tastes like a million bucks!" OR "Raise anchor, and pour me another yachtsman."
