Tricking someone into clicking on a link against their well.
You want your friend to see twogirlsandacup.com, but you know they won't click on the explicit link. So you disguise the link via a link shortener like TinyURL or Bit.ly and send that link to them instead. If they click on the shortened link, you are a linkrapist and they have been linkraped.
The process of posting an incessant number of links to someone's profile on a social networking tool.

Ryan: "Yeah sorry, I totally linkraped you"
