They taco the best balloons
As Kool AD explains in the next line, balloons are breasts, and to “taco” them would be them to fold them around an object like one would fold a tortilla around cooked food to make a taco. Presumably the object is a penis, ie Das Racist is down with titty-fucking.
Note that Jeff Koons (prev. line) is famous for huge shiny balloon animal sculptures.
