I got told that people thought it was a british saying, but no one uses it! I guess it must be because of HP... I feel like watching hp actually... haha.
Omg when i first started my new private all girls school at 7 I got snogging and shagging mixed up. So told all the girls i'd shagged so many guys at my old school (we used to play 'kiss chase' loads ahahah) and they were all horrified!
yeah i was a bit of a babyslut before i moved to the all girls school and this game we played - you had to run around and catch and kiss as many guys as you could.
