What do you consider to be the top of the bat?

Me and my father just got into a debate where he thinks that the top of the bat would be the handle and the bottom being the barrel.

I on the other hand think the handle is the bottom and the barrel the top making "choke up" mean move your hands up on the handle to the "top" meaning towards the barrel.

I know im right but sometimes you just cant convince an old man that he's wrong
