Code word frequently used by high school students to mean cocaine. (Pepsi = coke = cocaine). Frequently used over telephone and instant messenger-type conversations.
Quebec, Canada, slang for French-Canadian. Based on Pepsi's early marketing as a cheap substitute for Coke. Early jingle: "Pepsi-Cola hits the spot/Twelve full ounces, that's a lot (Coke had 7 ounces)/Twice as much for a nickel, too/Pepsi-Cola is the drink for you". The slur was that French-Canadians were also cheap imitations.
Pepsi doesn't have enough Pep, it has more 'Si' also known as Coke's codename, if it weren't for Pep there would be only be 'Si'. Wage the war on Coke my Pepsi brothers, now grab a Pepsi filled with bullets and kill those Coke lovers! WE WILL KILL THEM ALL!
