Am I putting some of my feelings on my daughter?

I have been in toxic abusive relationships and all I want is my daughters to not go through the same the same thing. My oldest is 20 and her boyfriend is 23. He came over the house and called her a rachet whore. It was obviously meant as a joke. What happened was he told her about how there is a video out there that he acted in when he was 13 about drunk driving and he was playing a teenager who was at a party and drank. You know those dumb educational videos. He finds it embarrassing because he clearly looked young and it was stupid and said his mom was just trying to show off his acting "chops". Idk what the means. But anyway. He told my daughter she would never be able to find it. And she did and posted a screenshot from it on Facebook saying he was so cute. He game over and when he saw her he said "You. Rachet.... Whore." And they bother laughed about he. He was asking why he was jump scared on Facebook but a screenshot from that old drive safe video. She told him "You challenged me and said I wouldn't be able to find it." He said he screamed out loud when he saw it and scared his roommate. Honestly I know it's a joke but part of my brain is like "What if he actually means it and is just trying to get her used to him name calling her." "What if he starts beating her." I get it's probably just their thing. I get maybe I'm being dramatic and pushing my trauma on to her. Can I get advice?
