There are two words that you should never use when asking a girl out. These two words might sound quite normal and innocent to you, but in the context of asking a woman out on a date – they are not, because these words are so weak and they make you appear so passive. These words are “hanging out.” When you ask a girl “Would you like to hang out sometime?” it sounds so purposeless, and so unromantic. Perhaps I assume too much, and I am taking this too far, but to me, hanging out is something that people do when they are bored and they are trying to figure out what to occupy their time with and no longer be bored. And you surely don’t want to make it look like you are asking a girl out by saying: “Would you like to meet and be bored together?”
Hanging out is something you do with your friends on a couch when you are watching a game or playing video games or drinking beer or doing whatever else to just chill and wait for the evening to be over. You may also be hanging out with your buddies on a bench – just sitting and relaxing. You generally don’t use the term “hanging out” in reference to something special that you are going to do and are supposed to be at least a little excited about.
There are so many other ways to ask a girl to go out with you, that there is simply no need to ever ask any girl whether she would like to “hang out” with you. And the only worse way to ask a girl out than asking her if she wants to hang out with you, is texting her the same question.
