The last name of the famous Slothshath. If he is is called without this word, he will summon the wrath of the sloth army on you. Better beware.
Person 1: Oh I hope Slothshath comes.
Person 2: Oh no... you just didn't call him without the "Gurtu-Bonobo"...
*Person 1 gets overrun and raped by the sloth army.
Person 2: Yep as expected, you get the sloth rape.
