I've recently been contacted by a very old friend who refered to me as a 'geezer'. Now I couldn't swear an oath on this, but I'd say what used to be a geezer has latterly become a 'dude'. For more guidance.... Might I suggest the followin:
A Beazer geezer = Someone who reads 1970's comics
A Breezer geezer = Someone with a taste for white rum mixed with a fruit based drink.
A Ceasar geezer = Any toga wearing megalomaniac.
A Freezer geezer = Will come round and repair your Electrolux.
