I am confused by the suggestion that the word "love" would indicate happiness. Usually when I use that in source code, I'm being sarcastic. As in, Don't you love the fact that Google's API documentation is inaccurate?
Maybe. It is possible that the word is used sarcastically more often than literally though. For instance, it wouldn't surprise me to learn that the word "literally" may actually be used more often to mean "not literally".
