He tells him is name is Nohbdy. "Nohbdy, Nohbdy's tricked me, Nohbdy's ruined me!" -Polyphemus or Cyclops
Telemus, son of Eurymus, foretold to Polyphemus that Odysseus would one day blind him.
Odysseus tells Polyphemus that his name is "Nobody" when asked for his name. This allows Odysseus to trick Polyphemus when he later blinds him and Polyphemus calls for help, claiming that "Nobody" is attacking him.
He tells him is name is Nohbdy. "Nohbdy, Nohbdy's tricked me, Nohbdy's ruined me!" -Polyphemus or Cyclops
Before Polyphemus (name means many loud shouts) is blinded by Odysseus, he asks him his name as he has a gift for him. Odysseus tells Polyphemus his name is "Nobody." When the other Cyclops ask Polyphemus why he is shouting and ask if he is being attacked, Polyphemus tells them, "Nobody is attacking me," so they all think it is an affliction sent by the Gods and tell him to pray to his father Poseidon for relief.
A prophet
Polyphemus is surprised by the fulfillment of the prophecy because he underestimates the cunning of Odysseus and believes his own strength and isolation make him invulnerable. The prophecy, which foretells that he will be blinded by a man named Odysseus, seems implausible to him, as he is a formidable giant. Additionally, he dismisses the warnings from his father, Poseidon, and is caught off guard when Odysseus cleverly executes his plan. This underestimation of both Odysseus and the power of fate leads to his shock when the prophecy comes true.
Though Oedipus tried to avoid his fate, the prophecy was still fulfilled.
Odysseus gets revenge on the Cyclops, Polyphemus, by using cunning rather than brute force. He tricks Polyphemus into drinking wine and then tells him his name is "Nobody." When Polyphemus falls asleep, Odysseus and his men drive a sharpened stake into the Cyclops's eye, blinding him. When Polyphemus calls for help, he tells others that "Nobody" is attacking him, allowing Odysseus and his men to escape from the cave.
That one, there!
The other Cyclopes think Polyphemus is saying that "Nobody" has tricked him. This is a clever play on words by Odysseus when he tells Polyphemus his name is "Nobody," so when Polyphemus shouts that "Nobody" has tricked him, the other Cyclopes do not understand that he is actually in trouble.
Polyphemus throws a rock at Odysseus's ship and almost sinks it, but instead creates a wave sending Odysseus and his men away from the island
