A Girl Goes On Holidays In Jamaica

She met a nice local and they start dating.
After a couple of days she tells him:
- I am sorry but you never told me your name.
- I can't, you'll find it ridiculous, I don't want you to laugh at me...
- Oh please, please, I promise. I won't laugh at you.
- Ok, my name is Snow.

The girl looks at him with a poker face but then start to laugh, and laugh.
- You promised you won't find it ridiculous, he says.
- I don't. It's just, I just imagined the face of my friends in Canada when I will explain I got 20 centimetres (8 inches?) of Snow in Jamaica...

Edit: Changed the name to just Snow.
