See over here you're never really referred to as a cracker or anything else derogatory (that I know of o.e) , well, mainly because where I live right now, the black population is SUCH a minority, to see one in a day you're like -"Oh- heyyyy!!!!!!"
But back when I lived in Halifax it was basically used to disapprove of you if you were doing something either
-Painfully White
Reference seconds 56-59.or
-slightly racist a.k.a. being an idiot.
luckily I managed to avoid being either in front of anyone who could legitimately use it. XD
But yeah I still never heard 'honkies' EVER, though 'Wigger' was around.
Though again never heard by me personally in anything other than a definition type experience.
