Cut each lime into wedges. Put 4 wedges in a short rocks glass. Add 2 tablespoons of sugar and muddle with a bar tool "muddler" (or use a spoon or pestle). Add a splash of mango nectar, to taste. Fill the glass with ice and pour 2 ounces of cachaca over the ice. Garnish with slice of mango and a lime wedge. Repeat to make 3 more drinks.
