Did afromans song colt 45 rip off sugar hill gangs rappers delight?

The answer is: yes

Rapper's Delight was released in 1979 by Sugarhill Gang. Colt 45 was released in 2001 by Afroman. Colt 45 is an obvious parody of Rapper's Delight. Multiple lyrics, rhyme patterns, and even the chorus and title are all copies.
