The AB is a type of fast food from Adelaide which has been popular with university students since its creation. It is made up of chips and yiros meat, covered with tomato, barbecue, garlic sauce and tzatziki. Its somewhat grotesque appearance is the source of the name "AB", for "abortion", or "after-birth" (it has also been known to be called a Dogs Breakfast in some other places in Adelaide). It is commonly eaten after or during a night of drinking, or as a hangover food. While $9 is the normal price for an AB, it is merely the minimum possible size: there are currently records in excess of $350-worth ABs being served and consumed.

Rivalry

Only two North Adelaide take-out cafés currently serve the AB; the North Adelaide Burger Bar (commonly called the Red and White) and the Blue and White, which are both on O'Connell Street within three storefronts of each other. Both claim to be the inventor of the AB, and both claim to make a superior AB to the other. The main difference is that the Red and White's AB includes tzatziki sauce whilst the Blue and White's does not.

Due to an inter-college rivalry between St. Mark's, who usually patronise the Red and White, and the other major North Adelaide residential colleges (St. Ann's, Lincoln and Aquinas), residents of those colleges tend to favour the Blue and White.

Numerous other takeaway shops in the Adelaide area have also started selling the AB's, although they appear under different guises. The 'Atomic Bomb' is available from the Fish And Chip shop on Marion Road next to the Tram line with a smallest serving size of $7.

Trivia

In 2005 the band 'Fix My Chariot' (from St Mark's College) won a $200 AB from the Blue and White Cafe in the inaugural Inter-College Battle of the Bands held by Lincoln College. This AB was consumed with gusto by St Mark's Collegians, notwithstanding their loyalty to the Red and White.
