This is a possible concise summary:
Markiplier, a popular YouTuber, invites his mom to play Five Nights at Freddy's, a horror game where the player has to survive the night in a haunted pizzeria. His mom, who calls herself Momiplier, has no idea how to play the game and makes funny mistakes like calling the animatronics by the wrong names. She tries to scare them away by saying "Boo!" and flipping them off, but she gets jumpscared several times and screams in terror. Markiplier laughs along with her and gives her some tips, but she still fails to beat the second night. She ends the video by cuddling with her dog Bubble and wishing everyone a happy new year.
