A catch-all racial slur used to refer to anyone not of one's own race or culture. Since it can be used equally by any race to refer to any other race, it's use cannot be censored or censured by political correctnessnannies, because it does not promote hatred against any specific racial minority.
Barack Obama is a gink. Queen Elizabeth is a gink. The Dalai Lama is a gink. To you, I'm a gink. To me, you're a gink. So now we've said what we think of each other, let's just close this deal, yeah?
A crabby, bitter and unattractive old person. Ginks tend to be impoverished, indignant urban dwellers with the same political and social leanings that they had in their 20s, who blame everyone but themselves for their myriad problems, and accost total strangers to air complaints.
Political demonstrations always seem to include at least one wrinkly, unsmiling, badly-dressed septuagenarian gink sporting a homemade sign and haranguing passersby.
