A viral video in which a british boy (14 or so) is in his mothers car , and he exclaims, "I'm in my mums car! Broom broom!". Then it cuts to a scene where his mum exclaims "Get out of my car!" then she grins. The final scene cuts back to the boy saying in a slightly whiny voice, "Mah." This video grew in popularity most likely because of how random, or how much of a poorquality video.
A catch phrase popularized by the video "My New Haircut." Said when someone is on a roll or in a state of extreme focus and does not wish to be interrupted by someone that he/she deems unimportant and irrelevant.
From "My New Haircut":
Guy at desk: "Sir, you have to sign in."
Guido: "Not now chief, I'm in the fucking zone."
Kindergarten Teacher: "Who wants to read the next couple pages of 'The Cat in the Hat?'. Let's see...Jimmy, how about you?"
Jimmy: "Not now chief, I'm in the fucking zone."
