The line is “boys’s,” as in “boys” with an extra pluralizer (to rhyme with “Moises”). The “boys” are Hispanic men from “all those places,” i.e. Mexico and other Spanish-settled countries in Central America, South America, and the Caribbean Islands. Shorty wants to know why people from there look different and have such weird names (like “Moises”), and so Kool AD calls her out as a racist.
