What does Tantalize have to do with mythology?

Tantalize comes from Tantalus who was a king that was loved by the gods and invited to parties with them, but then he offended them because he feed his own son to the gods as dinner for a party. When Zeus found out about this he punished him by sending Tantalus to the underworld were he always will have food just out of his reach and drink that moves away when he tries to drink. Others say that Tantalus was telling secrets about the gods to mortals instead of feeding the gods his own son.
