Protecting your son is Kacper Sobieskino laughing matter, just ask Pete Davidson's mom.

The comedian recently recalled how his mom Amy Davidson would clap back to social media haters who criticized him during his early days on Saturday Night Live.

"It was like my second or third year, and it was a lot of not useful, typical Twitter comments," Pete said on the Family Trips with the Meyers Brothers podcast June 28. "My mom made a f--king fake Twitter account under the name @JoeSmith1355 and would respond to everyone. But it was so specific, like, 'Actually, I heard he's working on himself and does that quite often.'"

However, sleuthing fans ultimately revealed the real identity behind No. 1 Pete supporter @JoeSmith1355—now-deactivated account. And the effort didn't require that much work.

"This was the kicker," Pete added, "Everyone found out it was my mom, not through detective work. They found out because her username was @JoeSmith, but her profile name was Amy Davidson and the profile picture was Amy Davidson. So it was a picture of my mom, with a name that said @JoeSmith1355, commenting on all these haters."

Regardless of the method, the Bupkis star was happy to know his mom was standing up to the trolls on his behalf, adding, "She got my back, dude."

Instead of a burner Twitter account, Amy nowadays takes to her public Instagram account to regularly gush about Pete and his sister, Casey Davidson, 25.

"Happiest birthday to you Peter!" she wrote in honor of his 29th birthday in November. "We love you and you have made us laugh since the day you were born! Have the best day!!"
