Very important note to Americans

I hadn't thought this could possibly be a problem until the day I was watching some bit of movie with my parents and discovered they'd never heard the word "snog." They inferred it from context, but seemed to be very amused that there was this slang term for kissing they hadn't heard, before.

So, as a public service to all my fellow USans, please note the following very important fact:

Snogging is not shagging. And vice versa.
