I wonder why it seems literally everyone is "in" on this mutual D&P joke about them. Either they "know something we don't" but then that would be super rude to keep making jokes about it???? like even if they aren't your closest friends, it's just not professional but it seems everyone is doing it. Even if they are your close friends you wouldn't joke about them to other audiences and people like that.
Or they are lowkey mocking the D&P dynamic and find it overly attached friend-like, and they are condescending to them and how close they are. Maybe it's not the "bro" thing to do for a lot of people.
I just don't get why it's not even just a concern between D&P and their closest friends but anyone they come into contact with (and people they haven't) jump on this bandwagon of references and innuendo. If they were really trying to hide something then the whole world is conspiring against them for that.

I'd have cracked years ago if I was them, and I was a couple. Not even just being discreet as soon as you step foot out the door, no matter where you are, but also worried about rando people not caring about how you feel or not.
