When you have sex with a girl and after words she tells you that she's only fifteen. When she tells you this you freak out saying the phrase "what do you mean you're only 15!"
When me and my girl finished having sex she looked at me and said "that was the best sex I've had in my fifteen years." I then responded with "only 15!"
