Someone with way too much time on their hands who gets a cheap thrill by clicking on Google Adsense, Google Adword and other Sponsored Ads on searches and websites that he knows will cost that company a paid click even tho he has no intention of checking out the site or the product. Especially likes to click on sites belonging to larger companies or porn sites, with the click representing a little f*ck you to that company.
When a clickster has nothing better to do, a clickster does random Google searches and clicks on the paid ads to cost those companies a few cents each.
A Porsche Boxster, from the habits of their drivers, primarily cocks. Cockster owners are famous for being gigantic assholes to cover up for the fact that they couldn't afford a 911, but still want to be as snobby as one a 911 pilot.
Usually justifies his spending via a discussion of how raw power isn't important, it is the raw feel of a car, handling, etc. May make reference (rightfully so) to how the 911 is still putting its engine in the wrong place, but do not be fooled by his pseudointellectualism, no matter his justification, nobody will buy a Boxster if they can afford a 911.
