What is the meaning of "cram your tram"? I don't quite understand this sentence.
Here, "cram" could be replaced with any insulting profanity, such as "screw". "Tram" here refers to a vehicle that travels on tracks (which is what the characters are in during this scene). The speaker is insulting the other character's "tram" and saying he doesn't care about the rules regarding the tram. "Cram" used as profanity is specific to this scene, and is not standard English.
