Wabbit

Wabbit is a nickname given to Hafidha Gates, presumably because her trickster personality is so much like that of Bugs Bunny.

Chronologically, the first reference to Hafidha as "Wabbit" appears to be her first LiveJournal entry:
 * "And so having disposed of the monster, exits our hero, stage right through the front door, none the worse from his harrowing experience."
 * --Bugs Bunny
