Chrisean Rock Punches Adam22 in Back of the Head Over Parenting Joke at Wild N' Out Show

Chrisean Rock landed a couple of punches to the back of Adam22's head at L.A.'s Wild N' Out show ... after he dissed her abilities as a mom.

It all went down at the Intuit Dome last night ... as part of the L.A. Team, Adam was up against the Wild N' Out team -- including Justina Valentine -- who mocked his marriage to OnlyFans star Lena The Plug.

When it was his turn, Adam clapped back ... "Justina, your BBL is embarrassing, but that's nothing compared to Chrisean Rock's parenting."

As you know ... Chrisean shares a son with her ex-fiancé Blueface -- who was the captain of Adam's team.

Chrisean -- who had a hoodie over her face -- slowly walked over to Adam, seemingly struck him twice in the back of the head, and then slowly walked away on her phone.

Speaking out about the incident, Adam shared a YouTube video of him icing his "incredibly swollen" jaw.

Adam -- who said he's considering filing a police report -- told his fans ... "I was attacked brutally early tonight."

Adam said that Chrisean -- who is a boxer -- was shooting him glances leading up to the joke ... especially since he's criticized Chrisean's parenting in the past.

After getting hit, Adam claimed that a security guard asked him to leave the stage, saying ... "We just want to make sure that nothing bad goes down."

Adam also alleges that Chrisean started "mean-mugging" Lena -- who recently reconciled with Adam after a separation -- after the incident that left his wife "freaked out."

Regarding his injury, Adam admitted ... "At the end of the day, this affects my work."
