WARNING: explicit language

AN AMERICAN high school student has been caught on video subjecting his teacher to an ugly, foul-mouthed tirade in a classroom, as the teacher calmly tells him to "go sit down".

Fellow students are seen sniggering as the enraged student at California's Eastside High School enters the room yelling at his teacher and continues his spray as the teacher calmly sits at the front of the room.

A high school student has been caught on video subjecting his teacher to an angry, expletive-laden rant.

"You do not come up to me Dr Hsu and get in my goddamn face," he yells as the pair both enter the room.

"You go there, sit down," the science teacher says, pointing to the back of the room, which further enrages the teen.

"You go sit down," he rages, becoming red in the face.

"You come up to me like that? Who the f*** do you think you are?"

When the teacher takes his own seat at the front of the classroom, he again tries to tell the student to take his seat in the classroom.

"I'm not f***ing playing," the red-faced student continues.

"Go sit down," the teacher says.

"Shut your f***ing mouth," he yells.

Other students in the classroom continue to snigger as the boy rips something off a tap and throws it in the teacher's direction and then kicks a garbage bin, which falls over.

He then picks up the bin and empties its contents on the floor.

School principal Kristen Tepper said in a statement the incident had been investigated and "appropriate action by school administration" taken.

The video, posted on Twitter, has been retweeted more than 800 times, prompting outrage.
