Slang Words for Vomit

The slang word for vomit is to spew SPEW. And its origins are more the south east of England. Although it is used in other parts of the UK now, but above all I identify it with working class London. Another typically British slang word is mug m-u-g. If you call someone a mug that means they're gullible. They're very susceptible to being tricked or fooled.
