K-pop
From Tardis Wiki, the free Doctor Who reference
The Eighth Doctor's gorilla companion Guy was fond of K-pop, which the Doctor disapproved of. Charlotte Pollard asked if this was a breakfast cereal, and the Doctor answered in the affirmative. (AUDIO: The Mummy Speaks!)
Behind the scenes
This is, at the very least as a misdirect, a reference to K-pop, Korean pop music.
