¿POPCORN is his real name?

It is interesting to see how all people know how to identify it, we know its flavor and where it comes from but why is it called differently in each country?
¿they have not asked?

for example:
USA: popcorn
Argentina: pochoclo
Chile: cabritas
Colombia: crispetas
Guatemala : poporopo
México : palomitas de maíz
Panamá: millo
Perú: cancha
Venezuela: cotufas

There is no answer to that question haha ​​my opinion is that it should be because as you change the accent depending on the geographical area can vary the way you see the delicious popcorn lol but I am rambling. If anyone knows, do not hesitate to comment because I would be interested to know. regards
