Bobba is the name of the notable word filter File:BobbaFilter.gif in Habbo that activates when profanities or dates are spoken in the hotel. Putting periods between the letters of the words will not trick the censor. It is possible the word evolved from Hobba (which in turn came from Habbo). It has been removed in the past, but in September of 2012 it was brought back as the official Habbo word filter word.
