This word is often combined with the word "minger" (unattractive woman), to form the phrase "chat minger" (disgusting unattractive woman), mainly for emphasis. There is much evidence of this sense of the word being used on the internet, especially in informal settings such as myspace.
Quote from a comment posted on myspace: "You're a chat minger and no body likes you... No one... Especialy(sic) your mum, she hates you the most... and she is right to do so. "
Are we missing a noun sense - some sort of leaf that is chewed by people in North Africa and the Middle East? SemperBlotto 22:36, 3 January 2009 (UTC)
I think you mean khat. It's from Arabic قات (qāt), so there are lots of alternative spellings depending on the transliteration. I don't know if chat is one of them, probably though. Nadando 23:45, 3 January 2009 (UTC)

A louse. Since it's slang, I guess that's the slang meaning of louse, but either way, I don't feel competent to try and find if there are cites for British slang.--Prosfilaes (talk) 09:03, 25 January 2014 (UTC)
No, "chats" were real lice in "Thieves' cant" according to the OED, but they can cite only other dictionaries. The word was still in use a hundred years ago (see firstworldwar.com: "Also commonly referred to as 'chats', Lice often spread disease, ..." and trench warfare on Schoolnet: "Lice hunting was called 'chatting'") Dbfirs 12:44, 25 January 2014 (UTC)
I can find one citation which uses the term, albeit in a mention-y way:
2013, Graham Seal, The Soldiers' Press: Trench Journals in the First World War (ISBN 1137303263), page 149:
Trench foot was a nasty and potentially fatal foot disease commonly caused by these conditions, in which chats or body lice were the bane of all.
This has a recent broader sense in MLE, technically covered by one of our definitions ("to talk of; to discuss") but used in contexts where it wouldn't be used in Standard English: e.g. "don't chat shit" (don't talk rubbish). Equinox◑ 03:20, 5 April 2014 (UTC)
