My grandfather came up with insults right at the spot, only in private, for all of our neighbours. I know them more by the names he gave them than their actual names since I never talked to any of them, some examples would be: "narices mochas" (someone with a nose that looks like it was cut at the tip), "codos largos" (long elbows, apparently the person had a disease that made that happen) and he would call anyone who seemed retarded or slow "encalmado" (basically someone that let's everything pass and don't pay attention), even me. Also very simple insults for very apparent aspects, like "viejo maricón" to a homosexual vendor.
