What is I Don't Like You In That Way?
1.
What a girl says to a guy "friend" when he tries to express feelings for her that go beyond friendship. When a girl has a guy "friend", this almost always means that he is interested in her, which is why he hangs out with her, but she almost always sees him strictly as a friend.
<Girl> You're a great guy, but I don't like you in that way.
*translation*
<Girl> You're a great guy, and you have all the qualities in a guy I'm looking for, but I'm not going to be your girlfriend. I will, however, use you as a basis for comparison for all other guys who hit on me, but I'm going to be with someone who is far less nice, and who is probably an abusive alcoholic. Then, if he doesn't work out, I'll move on to another guy, but still not you. In fact, I will never be with you, but I will call you from time to time to complain about the guy that I am with.

A nice girl’s way of trying to spare your male fragile ego instead of saying flat out that they don’t like you and probably want you to leave them alone.
Nice Guy: So do you like want to go on a date with me friday night? *man I really want a piece of that ass*
Nice Girl: I'm sorry Charlie, I don't like you in that way.
*This guy is creepy, I don't want to offend him, he might turn into one of those stalkers.*
