Chances are you are thinking of the poem Jabberwocky by Lewis Carroll. It's very charming. An alternative theory would be that Jabba Wackees is a support group for people who have been whacked by Jabba the Hutt. But it doesn't seem too likely.
The jabbawockeez is aslo the name of a hip hop dance crew that won 1st prize on the first season of America best dance crew.
