It's been a part of our vocabulary for a long time now, but it's finally official.
Look up the word "WAG" in the dictionary and right beneath "to move from side to side, forward and backward, or up and down, especially rapidly and repeatedly" you will find the definition of the word you are more familiar with:
"The wife or girlfriend of a famous sportsman."
The word "sportsman" sounds like somebody who goes into the forest and chops down trees, but I think we know what they're talking about.
To commemorate this momentous occasion, I have compiled a list of the 100 most famous WAGs of all time. Keep in mind that these aren't necessarily the hottest, but rather the WAGs that made the word popular enough to make it into the lexicon.
The English language is forever in their debt.
