John Stamos' Son Billy Nicknamed Him 'Poopy' For This ADORABLE Reason

"Full House" star John Stamos recently disclosed what his four-year-old son, Billy, preferred calling him these days. The actor initially got recognition for his 1982-1986 role in "General Hospital." Stamos went on to star in "Full House" and reprise his role in the spin-off, "Fuller House."

Stamos has often talked about his son and how much the four-year-old meant to him and his wife, Caitlin McHugh. The 59-year-old previously shed light on how his role in "Big Shot" and his relationship with his young co-stars influenced how he wanted to raise his son. He explained he would teach Billy to be more "kind and loving" despite his privileged background.

Stamos joined an October 12 episode of "Live! With Kelly and Ryan" where he talked about Billy, his four-year-old son. The actor shares Billy with his wife McHugh, who he married in 2018 after two years of dating.

During the interview, the hosts, Kelly Ripa and Mark Consuelos talked about how well Stamos seemed to have adapted to fatherhood and revealed this version of the actor suited him the most. Ripa said, "I have to say that in all the variations of John Stamos I've known over the years, watching you become a dad has been my favorite one."

The 59-year-old went on to reveal that he cried a lot with his son, Billy, and described the four-year-old as the light of his life as well as his wife's.

Once he got on the topic of his son, Stamos powered along, revealing the "new thing" the four-year-old was most fascinated about recently. According to the 59-year-old, Billy was obsessed with the word "poop" and liked saying it "all the time."

Stamos explained his son loved the word so much that he had started including it in regular everyday conversations. "His new thing is that he likes to say 'poop' all the time," the actor said. "I was trying to teach him a knock-knock joke," and he kept finding a way to insert the word. [He goes,] 'knock, knock?' 'Who's there?' 'Poop.'"

He added that Billy regularly yelled out "Hi poop" despite his attempts to tell him the word wasn't particularly appropriate. "I said, 'Well, it's not appropriate to say 'poop' at school or talk about poop at school,'" Stamos added. "He said, 'well, what if I go to a poop school?' He's smart."

Stamos recalled a moment he shared a FaceTime call with his son some time ago, and the word popped out yet again, however, in a different variation. He revealed that while telling the four-year-old good night, he told him to look at the moon. Stamos, who wasn't home with Billy that night, promised to do the same.

"And then he said, 'Daddy, I can see your eyes in the moon,' and I said, 'Son, I can see your eyes too.' It was that beautiful moment, and I said, 'I love you, Billy.'" In the heartfelt moment, the four-year-old responded with as much feeling, "I love you, poopy."

In an interview with E! News, Stamos talked about his relationship with his younger co-stars on "Big Shot" and how working with them gave them some insight into their lives. The 59-year-old went on to reveal that the relationship had some effect on how he sought to raise his son with his wife.

The "Full House" actor joked that the four-year-old was yet to find out just how "cool" his father was; however, Stamos intended on keeping him as grounded as he could despite his privileged upbringing.

"I just have to lay the foundation of being loving and kind and teach him to be that," he explained. "I think we're pretty good examples, my wife and I. The hard thing is he lives a pretty privileged life. [My wife's] great, she takes him down to feed the homeless in Orange County, and we take him on stuff like that. We try to show him it's about service and giving back."
