2.) a fan of the Ratchet & Clank series in general. Rarely used; must be quallified as NOT being a fangirl

Originates from the words fuzz and otaku. However, unlike otaku (which has negative connotations), refering to someone as a "fuzztaku" is normally considered friendly and will usually prompt a response of "Yup! ^_^" or something similar.
