2014 marks the 20th World Cup football (soccer) tournament, and where there's football, there's WAGs. That's 'wives and girlfriends' to those not familiar with the term.

The acronym became prevalent during the 18th FIFA (Fédération Internationale de Football Association) World Cup Finals in 2006, when the British press began using it to reference the lovely lady friends of their national team's star players.

The World Cup Finals, now underway in Brazil, are played every four years and features 32 teams from nations around the world split into eight groups of four teams that play in a round-robin tournament and advance, ultimately to a final championship game.

Over 200 teams around the globe spend three years qualifying for the finals, which are held every four years.
