Someone with red hair is said to be ginger. Ginger hair is seen as a curse in Scotland and people with it will say they have red/strawberry blonde hair instead of admitting to being ginger - like my mum.
"The worst thing it is possible to have. It is believed to have originated when some Egyptian god or other decided that bad people deserved to have a ridiculous
colour hairdo. When shaved can often be mistaken for a Scotch egg."
"Yer maw's a ginge AND she huz ginger freckles!" "Shut it!"
Disclaimer: I ofcourse have no problem with ginger people.
