This snippet opens with Vern recounting a story about a friend whose father works for BVG, the Berlin public transport authority. The core of the anecdote revolves around a supposed white train that can no longer be tagged by graffiti artists. Vern frames this as a significant diss because, in the graffiti world, a white train is a coveted canvas that every writer wants to hit. The idea of a train being rendered un-taggable, especially if it's white, seems to be the punchline or the point of contention Vern is trying to make to his listener, Dany. Dany's immediate, sharp interjection, "Ey, ey, ey, was sagst du da ey?", suggests disbelief or strong disagreement with Vern's narrative, cutting off Vern's attempt to elaborate on the story.
