vadding

Vadding is a verb which has become synonymous with urban exploration.

A few go so far as to learn locksmithing in order to synthesize vadding keys.

Thus, vadding and vadders began to refer to people who undertook actions in real life similar to those in the game.

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.

Since ADVENT was all about exploring underground tunnels, the MIT sport of roof and tunnel hacking became known as vadding.

The most extreme and dangerous form of vadding is 'elevator rodeo', a.k.a. 'elevator surfing', a sport played by wrasslin' down a thousand-pound elevator car with a 3-foot piece of string, and then exploiting this mastery in various stimulating ways (such as elevator hopping, shaft exploration, rat-racing, and the ever-popular drop experiments).
