Froster is a brand of iced frozen carbonated beverage (however, not carbonated in Canada) sold at Mac's Convenience Stores in Canada and Circle K in the United States.
In 2006, a Froster advertising campaign was run that features a Froster flavour called "Whack". The campaign centres on the Whack flavour and uses double entendres involving the word, such as "I think I could have a Whack every day if I could," as well as humorously bleeping out the word "Whack" in the commercials.
In May 2007, Mac's introduced a controversial advertising campaign for their new WTF Froster beverage. Targeting primarily internet savvy teenage youth, the campaign included posters and a series of viral internet video ads. The controversy stems from the use of the WTF internet slang acronym "", a poster of a nun and goat bowing in the presence of a cup of WTF and video ads portraying sexual innuendo and bizarre or questionable conduct. In response Mac's has pulled the more controversial ads and has stated that it intended WTF to refer to "What's the flavour?".
In 2008, another controversial Froster advertising campaign was launched that uses the acronym "STFU" (which in stands for "shut the fuck up"). The website states the acronym means "suck the Froster up".
As of August 2014, the current campaign is "Take It Easy".
The official Froster website lists the flavours:
Other flavours do exist, such as Pepsi. Typically, older Mac's stores will not use "Fanta" or other technically correct names. It is quite common to find Crush labelled flavours, as well as flavours named as bluntly as "Banana".
