I've literally heard it called pop once in my life here in New Orleans. Some old lady in a Wendy's drive thru asking for a pop and the chick working the drive thru had no idea what the old lady talking about. Held up the line and everything. 
I've always heard it called coke, cold drink, or soft drink down here.
