Despite the negative connotations this word has attracted in more recent times, this is historically a general term used in the Portsmouth dialect. It is in no way chavvy, save for the fact that most of the real Pomponians left in Portsmouth these days pretty much are chavs.
A more endearing term is "mushty" or "mushdy", often rhymed with "cushdy", which expresses more of a friendly level of acquaintance.
A term that is used to greet others mostly in the south coast of England, UK. It’s mostly said by local people in the city of Southampton and the surrounding areas up to Portsmouth and Bournemouth.
