Except that is not what is implied at all. While I’m really not a fan of the phrase, it is a harsh, harsh (HARSH) generalization and swooping insult to say everyone that uses the phrase thinks they’re god’s gift to all of their objects of affection. Plus, if we’re going to take it there, why go ‘ew’ at people, however different their use of lingo (or as you’re clearly implying, appearance in relation to whoever they find attractive)? That’s as much, if not more, of an offensive snap judgment as emptily declaring “you’d hit that”. Not that I have an issue with either, but if you’re preaching it, then practice it.
