When talking freaky to someone, that can mean two different things. In a literal sense, you can be talking about weird and odd things to someone that not many others may want or even know to talk about. In the other sense of freaky, you can be talking highly sexual things to someone you are in a relationship with, or are courting. You want to be careful not to be too extreme in either sense of freaky as it can scare someone away or insult them to a point of seeking help.
