"I once was infatuated by the things that you do/But now you're doodoo" -Big Daddy Kane
Song: Big Daddy Kane "No Damn Good" (1990)
Using the word "doodoo" is bad enough, althoug there are isolated instances of using the grade-school insult effectively (i.e. "Scenario"). But rhyming "doo" with "do"? Rakim would never.
