vadding การใช้

Since ADVENT was all about exploring underground tunnels, the MIT sport of roof and tunnel hacking became known as vadding.
Thus, vadding and vadders began to refer to people who undertook actions in real life similar to those in the game.
This practice was once called " vadding " at the Massachusetts Institute of Technology, though students there now refer to it as roof and tunnel hacking.
Today, the word vadding is rarely used at MIT ( usually only by old-timers ) and roof and tunnel hacking has returned as the preferred descriptive term.
