Yeah, 'cause I owe you a knuckle sandwich.

对！我想你需要饱拳一顿。

You might see in a movie, we don't really use this in daily conversation, hopefully not too much, but you might see in a movie, someone say, do you want me to give you a knuckle sandwich?

你可能会在电影中看到，我们不会在日常对话中使用这个，希望不会太多，但你可能会在电影中看到，有人说，你想让我给你一拳吗？
