"Excuse me but what are you doing?"
"Your Mum/mom"

"What are you having for breakfast?"
"Your Mum/mom"

"What is your Mum/mom's name?"
"Your Mum/mom"

A term exclusive to pre-teens and individuals below the age of thirteen, exceptions are made for lowlifes and socially incompetent adolescents when faced with a challenge, (typically a relative, since individuals whom use this term haven't moved out of their parent's house) standing between the individual and their gaming.
This game is exclusive to minecraft naturally, however these gamers still remain dominant over the peasants whom still play fortnite
Get a life.

Karen is never coming back.

Calling Mom

An alibi for jacking off without being interrupted by a nosy roommate. Often serves as a replacement to fixing a broken lock or crooked bedroom door.

"No, I don't think Drew can come to the pool with us. He's calling mom and you know how chatty they get. We better just leave him alone in his room for the next few hours."
