Same, but with peonzas/trompos[0]. It's interesting since it's also about breaking the other player's item thanks to the inertia provided by a string.
In short, they're hardcore spinning tops: large, generally with a metal tip, spun much faster due to the string winding, and as mentioned, the objective is to crack the other player's.
