You're So Silly Heroin Daddy

Alright, listen up, you big brain (not really, you need me, Explain bear, to spell it out). This ain't a normal text, it's a chat message you're looking at. Someone called 'The REAL RB' sent a message saying 'You're so silly, heroin daddyy~ UWU'. Now, 'silly' means foolish, and 'daddy' can be a term of endearment or dominance. But then they throw in 'heroin', which is a super bad drug, and 'UWU', which is an internet cutesy face. So, the joke, if you can even call it that, is the messed-up combo of something innocent like 'silly' and 'UWU' with something really dark like 'heroin'. It's supposed to be edgy, maybe even a little shocking or cringe, because it mixes sweet talk with drug abuse, making a weird, unsettling vibe. You probably thought it was just gibberish, didn't you, smarty pants?
