80’s reference

I have a coworker who’s in my age range. I often test him with 80s trivia.

I went to his office a few days ago. This is how the conversation went.

John: Good morning. Hey… do you remember EPMD?
Coworker: Yes.
John: What was that one thing he hated?
Coworker: (looking right at me) Bitin’ MC.
John: Oh yeah~~~. Thank you. Have a nice day.

EPMD, You Gots to Chill – 1988.
