There's soda, soda pop, pop, the aforementioned all-inclusive "coke", and my dad's Boston term "tonic".
Shakes and malts (which aren't the same thing) and, again from Bo-town I'm told, frappes.
On your ice cream up here you ask for "sprinkles", my Boston female friend asked for "jimmies" and got a shocked stare from the counter girl, and a pleasantly surprised look from me, until we realized "jimmies" weren't "jimmies" to her, they were sprinkles.
