My boyfriend won’t stop saying “ambatukam” during sex and I don’t have the heart to tell him I hate it

One evening, me (F22) and my boyfriend (M21) were watching memes on YouTube from his phone, something we frequently do together. He REALLY likes memes and quotes them often throughout the day, no matter whether he is happy or being goofy and even when he is raging at a game or genuinely heartbroken. One day about a year ago, he came home to tell me he got fired and said “my life be like oooh aaah”. It’s probably a coping mechanism for him, but personally I do not understand it.

Anyways, we saw one meme, a guy a clearly masturbating saying things “I’m about to cum” but it was spelt out as “ambatukam”, and thought it was the funniest thing ever so we looked for more. There were more videos of him being edited into scenarios like him mourning the loss of his brother named “Bato Khan”, and we spent no less than 20 minutes laughing nonstop at these videos. Afterwards when we went to make dinner, my BF said joking “that’s what I’m gonna say in bed now”.

Fast forward a day later, both of us are horny and head to the bedroom to fuck. It was great, but then towards the end, my BF said loudly “ambatukaaaam” and then proceeded to cum. I laughed along with him but I was a little uncomfortable because it sorta killed the vibe.

About a week later, we’re having sex again, and he says them same exact thing as last time, but this time, he laughs “just kidding, I’ll stop” afterwards. Well, it turns out he wasn’t really telling the truth because the next time we had sex, he said “bouttobus”. I then whining-ly said his name in desperation and he then chuckled.

We didn’t have sex for about a month until last night. We were doing fine as usual, and he even managed to cum without saying any memes… or so I thought, because right afterwards, he said something along the lines of “thank you for letting me buss, it’s what I needed”. I can’t even remember much of what happened during or after that because I was in pure shock that we would just kill the vibe like that again. All I remember is that we cleaned up and he went to play COD or something that involved him shouting stupid jokes and memes to his friends.

I do not have the heart to tell him that he isn’t funny when he does this, because the last time I confronted him when he kept saying “yooo that’s sus” every time I mentioned something vaguely sexual, he almost cried. He stopped saying that one phrase but still has about a thousand other memes in his vocabulary. I guess this is just my life now, and as much as I want it to stop, I love my boyfriend so much and will have to live with it.
