5. C2
The new coca cola with half the calories and sugar or regular coca cola. This is due to the fact that regular cola is mixed with diet cola 50/50 thus making it half calories and sugar. Half of full sugar + half of no sugar=half sugar. Thus giving C2 its shitty taste
C2 is shitty because it is Diet Coke mixed with Regular Coke

Supposedly Coke with half the calories and half the carbs, but in turn is the grossest thing you could ever drink.
