A term created by the Nintendo focused YouTube content creator known as failboat. The term is used for the Nintendo Switch game, Super Mario Maker 2 and it refers to someone with poor internet connection in the game.
When your mom trips and falls while holding cereal, causing it to spill all over the floor, your dad then proceeds to say, "BEEB!" (Mom's Name is Really Bebe) while your mom says, "PETE!" (Dad's Name) thinking he is going to help her up, he then turns around and screams, "THE CEREAL!" While being upset that it is harmed and not helping your hurt mother off of the hardwood floor. This isn't a nice action.
