around here its usually "pop", often "coke", and occasionally "soft drink". any lemon lime cola is called "sprite" and some places will aske you is 7up is ok lol at a restraunt though you call it pop or soft drink, if you call is coke you will get a coke lol or you will get asked if pepsi is ok lol but for the most part the word is "pop" differnts kinds are like "orange pop" kinda thing you will NEVER hear someone call it a "soda" around here lol so thats the one that sound goofy to me but really if you think about any word or name to long it will start to sound really goofy lol
