I've had some pretty epic hickies left in my time. I've also left them theres photographic evidence of my ones around. Personally I quite like the receiving or giving of hickies, especially if they're actually done in the throws of passion, means you're doing it right. The only complaint I have is, some people have this idea that if I've got a love bite it's perfectly good to go "Oh case of low flying bats was it?" I'm sorry you know what it is, if you know who it was then well, shut up because it's not awesome to ask stupid questions. However if you don't know who left their mark ask outright "So who was she? And more importantly, will she be doing it again?" because we're damn adult enough to speak like that.
