It's from back in the poalcast days when one of the poalrs (can't remember who) lived near railways and trains would fucking honk when he was speaking, thus making it impossible to understand what he was talking about. And he was like "fucking trains" every time they would honk. We had a good laugh about it and that's why it even ended up in Poal's rotating slogan. What's even funnier is that before we had vid8, we used a self-hosted invidio.us instance called Poaltube to share/play jootube videos on poal. Its main dev got triggered by that "fucking trains" slogan and asked us about it (thinking we were attacking "trans"). Boobs tried to explained him in the chat, but he didn't believe him and left. lol
