c2
A "c2" is a word used for a slut or permiscious girl. Or when used for guys it means a threat. It was derived from counter strike source when if the button c then 2 was pressed you would tell your teammates "enemy spoted"
When refering to girls: "Oi bro check out that c2 there. Damn shes hot."

When refering to guys: "Check out the c2s that jus walked in."

The use for girls is the most common.

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
