Okie Dokie it's day 3 and I promised these hints would get easier so tonight I will give you the first word of the drink and recap the previous hints.
Previous hints:
Hint #2: It is cold and proprietary to a
particular store.
Hint #1: It's a type of drink
not just a brand name (like: vanilla milkshake, root beer float, or dirty martini) so answers like coke, mt.dew, and milk aren't going to cut it.
Tonight's Hint - Hint# 3: Coke _______
Tomorrow is the last day so around 12am Central if we still don't have a winner I will post what it is and the next person to reply with the answer will win.

I have faith we'll get a winner today though, some folks have already been crazy close.
