What does 436 mean in texting?

I'm curious, could you please clarify for me what the number 436 signifies in the context of text messaging? I've seen it used in a few messages recently and I'm trying to figure out if it's some sort of secret code or has a specific meaning? It's intriguing and I'd really appreciate it if you could help me understand its meaning. Is it related to some popular slang or culture trend? Or is it just a random number that people use for fun? I'm quite puzzled by this and would love to get to the bottom of it.
