Introduction

The use of "woah" has the ability to transform a ragtag group of Ridazz into a frothing pit of bike insanity in a matter of moments. "Woah's" infectious nature has caused its use to be banned in small sections of Southeast Asia, along with the possibility of being added to the FBI's "most dangerous word's list." However, "woah" is such an important phrase in bike culture it was used for the entirety of a CubCamp ride in 2007.

Observe this typical conversation and notice how E-Rock's usage of "woah" transformed you completely:

-You: "How are you doing?"
-E-Rock: "I'm doing Rad woahwoahwoahwoah"
-You: "Woooooah"
-E-Rock:  "woah"
-You: "WWWWAAAOOOOAAAHHH"

Please experiment with "woah", but remember to be careful...
