h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Something I just thought about: Scally language.

The scally universe seems to generate new slang words every now and then. The first I can recall is "better" to mean "very good". As in, "Wah, deez traineez are better!", meaning, "Oh my, these training shoes are rather exemplary".

Around the same time came the phrase "Buzzin'" also meaning "very good", or to describe a good feeling. Example: "How was the football game, kind sir?"
"Buzzin'!".

The two could also be combined into one superlative. Example: "I went to Blackpool last week."
"What was it like?"
"Better buzz!".

The only others that come to mind which appeared after the aforementioned phrases died out are "pure" and "raw" to mean "good" and "bad" respectively. These phrase lasted a long time and may still be in use today.

There was also one more I remember which was "sell", used as an imperative, which came and went relatively quickly. Example, "I ordered a pair or trainers and two arrived in the post!".
"Ah go 'ed, sell! Sell!" (translation: "Really? I would be most interested in purchases those extra items.").

This information is mainly garnered from nephew who is that absolute cliche of a scally.
