A rich, entitled, generally (but not necessarily) white male who has "broken free of society" to live in a luxury Sprinter-type "van" in order to pursue various extreme sports at a relatively low level. They are generally seen drinking gourmet coffee while working on their personal branding, spraying questionable beta to anyone within earshot, and shouting "send it!" on beginner routes.

Ugh, the Buttermilks are full of vankerouacs triple padding the Ironman Traverse today. Let's go to the Sads.

I wish that vankerouac would spend more time actually climbing the route and less time posing for shots for their Instagram. Other people would like to try it.
