Fizzade was a brand of drink.
History[[edit] | [edit source]]
A vending machine in the Red Kang brainquarters of Paradise Towers carried the Fizzade brand and the Seventh Doctor used it to get himself a drink, much to the amazement of the Red Kangs.
After tasting it, Fire Escape declared the drink to be "ice hot" — i.e. cool (excellent, impressive). Soon, all the Red Kangs were using the vending machine and drinking Fizzade. (TV: Paradise Towers)
