More than just lame nerd speak (which would correctly be nerdonics). Nerdbonics is used for gangster internet nerds, thereby necessitating the extra "b". One can never self-identify as a gangster internet nerd. An individual can only gain the use of the extra "b" through repeatedly using lame internet based portmanteaus, having a google reader following of at least 15, or possibly actually taking the time to accurately define nerdbonics in urban dictionary.
In Google Wave conversation:
Padraic: "I have so many followers on google reader
. The internet is much better then the meatspace
. I bet you have a filthy memory hole
Witty commentator: "Nerdbonics.. holla!"
