According to the Economists Intelligence Unit, America ranks 17th in education out of 40 counties. Perhaps it's because when it comes to vocab, we aren't too picky.
Three hundred new words that have clear definitions have officially been added to dictionary.com
One of them is the word 'hangry', which refers to a state of being where you are so hungry that you get angry.
'Dad bod' is another term that basically describes Leonardo DiCaprio on the beach, but may also include George Clooney who is having twins soon. Other words include friendiversary, alt-right, mic drop, slay and sext.
