Babagaboosh

Could be referring to many things :

Babagaboosh is the catch phrase of Sam 11 from [Https://www.youtube.com/watch?v=W3id8E34cRQ I forced an Ai to play a kids adventure game] after he started speaking nonsensical sentences when his brain simply could not figure out how to enter Darkness' house before his inevitable demise.

For the rest of the story the catchphrase was picked up by his younger brothers ranging from Sam 12 to Sam 25. All but the latter of which died at the hands of the incompetent player named DougDoug, May they all rest in piece.

Babagaboosh (witch) is an evil witch referenced in the Waltown storyline which puts a curse on the 3 protagonists which causes a random twitch chatter to control the character.
