The son of a friend (now aged 9) came home from a "street dancing" club and began dancing around the living room singing "I@M SEXEEEEE"
Amused my friend's DH asked his DS if he knew what "sexy" meant.
"Yes" said his DS "Sexy is when you snog a girl and then sniff her under the armpits"!
Now if only I had realised that when going through all those fertility tests!
