That's pretty much spot on (more generally, I think it's a Central-American thing). Either "pelotas" or "bolas" are the common ones in South America (huevos is present, but rarely used in the same way—"huevón" is the classic insult used throughout).
Interesting. My dad is Uruguayan and I have not heard him use it (perhaps a biased sample?). I’m Venezuelan, for context, so it may explain this view :)
Venezolano y nunca ha oido un argentino decir "ponga huevo" "dejame de romper los huevos" ay chamo te van a quitar la cedula, Maduro, pero si tu viejo es yorugua capaz alla usan mas pelotas entonces.
