<human>: Can you condense the text into three sentences or less?

As always, this happened yesterday. I was playing Destiny with my cousin and some friends on XBL. My cousin was being really quiet and one of my best friends says "I don't think I can trust him, he's being too quiet." I try to say something we always joke about (since my cousin is of German decent). I try saying "You can't, he's a Nazi!" In an Old Man Herbert voice. Well, I start getting shot at right after the "can't, he's" part and my distracted brain's word association game replaced "a Nazi" with "a Jew". I immediately realized what I had said and broke into a cold sweat. My buddy goes "Wow, Bear. Wow." I tried explaining what happened, but there is no way I can prove that I didn't mean to say what I did. He blew it off as no problem and played for a bit longer, even said he wasn't mad when I spoke with him later. How could he not be, though? I have no way to prove that I didn't mean to say it and that in the moment of battle I just forgot what I was trying to say and spouted out what came with the word association going on in my head. I was awake until 5 am cringing over this. Any ideas on how I can remedy it?
<bot>: Got distracted while trying to say "Nazi", and ended up saying "Jew" in front of one of my best friends who is Jewish.
