according to this:

http://www.urbandictionary.com/define.php?term=Giffer

The "urban" dictionary

You and I are giffers, Vultan! I have always used it as an alternative to a 'geezer' or 'git'.

Although using Rasputin's link, I'd just like to say that I believe it is the first definition, rather than the last (description of a cap wearing old person (victor meldrew)a cross between git and duffer. ). Otherwise, it would not be you, but your wenches that are indeed the giffers.

A combination of a git and a duffer. If the cap fits... I'm wearing it!
