White student calls her mom after slapping teacher: ‘She’s Black and she’s pissing me off!’

A viral video shows a white high school student in Texas assaulting a Black teacher before calling her mom from the classroom and saying: "She's Black and she's pissing me off!"

According to Smash Da Topic, which posted the video Friday, the incident occurred at Castleberry High School in Fort Worth.

The video begins with the student walking toward the front of the classroom, where the teacher is apparently making a call on a landline phone.

The student appears to reach for the button on the phone to hang it up and end the teacher's call.

When the teacher tries to push the student's hand away, the student slaps her on the arm and says, "Deal with me!"

"No, no, no" the teacher can be heard saying. "You touched me. I did not touch you."

The teacher appears to ask the student to leave before walking away toward the door.

But the student doesn't follow her. Instead, the student picks up the phone and begins to dial.

When the teacher comes back and reaches for the phone, the student says, "No, I'm calling my momma. You ain't about to f*ck me up, b*tch."

After reaching her mother, the student tells her, "I need you to get over here now because this teacher's about to get f*cked up if she doesn't get the f*ck away from me. ... You want to talk to her because she's Black and she's f*cking pissing me off right now?"

The student then abruptly throws down the phone toward the teacher, but it appears to hit the ground.

The teacher, back seated at her desk, calmly picks up the phone and places it back on the hook as the student storms out of the classroom and the video ends.
