Technically not a word but things don’t get more official than making an emoji the Word of the Year by Oxford Dictionaries. The specific emoji is best described as “Face With Tears of Joy”. Oxford Dictionaries explains their decision stating the emoji “best reflected the ethos, mood, and preoccupations of 2015.”

“Emojis are no longer the preserve of texting teens.Instead, they have been embraced as a nuanced form of expression, and one which can cross language barriers.” -Oxford Dictionaries
