"Rail off" is a slang expression that is used to describe a situation where someone is speaking passionately and intensely about a topic. It is often used when someone is talking non-stop, without taking a break, and seems to be "on a roll". For example, if someone is talking about their favorite sports team and they keep going on and on about all the great players and memorable games, you might say "Wow, you're really railing off about the team!" However, it is important to note that "rail off" is a very informal expression and is not commonly used in more formal or professional settings.
