What does 'doff' mean?

It means to take off, it normally refers to a hat, but I think you can also doff your shoes and coat :)

I think it's olde English but I would have to check that. It means to take off or remove an item of clothing, usually a hat. Not really used now but I think it was more in use for polite company, eg. if you were to meet the Queen, you would "doff your hat" but it wouldn't be suitable say if someone was having their clothes cut open in hospital after an accident. It would be inappropriate to say "we're doffing your clothes"

in my country (SA) it means your stupid short for doofus
