A dumbass, likely of incel lifestyle. A (taken-back) slur one would once call someone that gamer-no life groups can now use in a joking way to ones own.
Former: You don't have any bitches! Go play Overwatch you Gink!
Current: You beautiful Gink come here and let me watch that pog.
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.
