Bobba
From Pool's Closed Wiki
Habbo, like many places that cater to spoiled underage brats, has a wordfiltering system and it's not used for lulz. Quite the opposite in fact. The censored temr used in place of the word is "bobba". It is believed to have originally been a codeword for AIDS, used among MODs.
The list of bobba'd wordsvaries from server to server. They also change over time, sometimes as a direct result of the nigra presence.
