Does the word "burger" have any extra meaning in some parts of the gay or lgbtq community?

I have seen at least 1 meme or other joke somewhere on the platform where one also mentioned a "twink" and where that word appeared to be the punchline somehow. I've scrolled through Urban Dictionary a bit (haha) and the meanings mentioned there are either literal, using burger as a metaphor for the kind of person who looks like they consume burgers regularly, as a random surrogate for things that are kind of round (haha) or even that aren't, or 1 Instance of fandom ship name for piece of media where the name of a character sounds like the word for onions in Japanese. That didn't really get me anywhere. Did I correctly pick up that I don't get it, or is there nothing more to this word?
