Artist Julius DuBose had said in an interview that when he began rapping, he was named A Boogie, a character in his fave movie 'Paid in Full.' Later, when he started wearing hoodies, he was called A Boogie wit da Hoodie, and the moniker stayed.
It is claimed that 50 Cent was a moniker of a gangster from Fort Greene Project. After the death of the gangster, Curtis Jackson borrowed the name. However, he has stated that his pseudonym is a metaphor for change.
Initially, 2 Chainz called himself Tity Boi. In 2010, he rechristened himself as 2 Chainz to become more family-friendly. He believes that his new stage name has a deeper meaning, and by adopting it, his rapping career had a rebirth. He has another pseudonym, Drenchgod.
