Luka & Schoolgirl CS Gas @ 1:42 In The Morning.

On the bus, a gaggle of schoolgirls was threatening another girl. One, the most vocal member of the gang, was threatening to gas her. She said loudly, in a triumphant manner, 'My name is Arkanna. Remember that name, so you will always be able to think of the time Arkanna told you, at 5:04 on the 86 bus, that you are a pussy, and you did nothing. You sat there and took it.' She said a lot more too, but i won't bore you with the details.

Schoolboys and schoolgirls attack each other with CS gas quite frequently. I don't know where they get it from. Maybe you can order it off the internet. It's probably better than being stabbed, but i doubt it's much fun.
