Have a twelve year old talk to you like that

There was a show or movie when they discussing a rude kid and after words the guy responds in a funny way “ I know it’s so demeaning when a 12 year old talks to you like that “”””

In like a funny way

Maybe the 12 year old beat the other guy in a online video game or something

But in very funny way

Any ideas anyone ?

Hi
There's a film "big shots" in the 80's with a verry rude kid.
Maybe it's this one.
See Trailer on youtube
