Joseph Tisi means in slang: He is a deadbeat lying liar and has done nothing over his nearly 50-years on the planet, with the exception that he brought eight children into this world. Although he was born with the potential for being a man, he chose to become a manipulative loser. He lies to all people about every topic and uses women to hide the truth. He wouldn’t be able to tell the truth even if it did, and it often does. But he isn’t aware of it. Because he has failed so badly as a father or man, he is too focused on himself.
