Reign Disick, 8, Thought Mom Kourtney Kardashian Should Name Her Newborn Son This NSFW Phrase

The mom-to-be was patient with her son's spirited suggestion

Kourtney Kardashian Barker's little guy has quite a sense of humor.

During Thursday's episode of The Kardashians, Lemme founder, 44, was doing a photo shoot with son Reign Aston, 8, on deck, joking about how he'd soon be a big brother.

"I'm gonna teach him how to play Call of Duty, Fortnight, teach him how to play Black Ops 3," Reign said, to which the expectant mom asked what if the baby was a girl.

"What if I have a sister? Still. She can be a cool person in her school."

"Wait his name should be Deez. His middle name should be Big, and then his last name should be Nuts. Deez Big Nuts," Reign told his mom.

"His last name will be Barker," she said, shooting him a look to indicate that she wasn't amused before adding, "Or her."
