A dialogue from a movie

Hello everyone. I have a question.

The below is a dialogue from the movie "Fighting with My Family." In it, I don't quite understand what the part "You feel it? You feel it cut..." means. I guess Ricky means to say "Do you feel it? If you feel it, cut the chokehold," but I’m not so sure. Could you please paraphrase it into formal English?

Int. Night. Young Zak and his sister Saraya fight over the remote control because they want to watch their favorite TV program. Zak is choking Saraya from behind as their father Ricky enters the living room.

Ricky: Zak! What the bloody hell do you think you're doing? If you really wanna choke her out, interlock the fingers.

Zak: Yeah.

Ricky: Now pull it tight. (Zak tightens his choke hold. ) Oh, yeah! Now she's in trouble. (To Saraya) You feel it? You feel it cut...(His wife Julia enters the room.)

Julia: What's going on.
