I read "Dula Peep" on a BuzzFeed quiz earlier and did some research. Apparently Wendy Williams was talking about famous singer Dua Lipa and mispronounced her name and it's kind of funny. Can also be found written "Doola Peep".
Dula Peep is a mispronunciation of famous pop singer's name, Dua Lipa, said by Wendy Williams, host of her talk show, the Wendy Williams Show. She mad this mistake in 2018 during a red carpet recap on her show. Wendy has constantly said it incorrectly and fans have begun using jokingly. It can also be spelled "Doola Peep".
