Who is a boy?

Go ahead and address your boy friend as a girl. He should not be humiliated though he will. In modern Tamil movies, it is a fashion to address male as female and vice-versa. This is an affectionate call.

But there is a history behind this. During the 13th century or up to that time, girl meant any young person, male or female.

Mostly, a female is known as a gay girl and a male as a knave girl.

Quite difficult even to imagine-eh? So, what's in a word?

There may be quite a lot of amusing facts in this category. Do you know any thing?
