We've gathered the most popular trends of the week for you.
Often described as the greatest Olympian of all time, swimmer Michael Phelps won his 23rd gold in the American men's 400-meter medley relay team, and his 28th medal overall, on Saturday.
Phelps suggested this could be the last race of his Olympic career, but what put him on top of our list this week was the face he made during training, which soon became a viral meme.
Phelps, thought to have been staring down at rival Chad le Clos of South Africa who was jiggling just a few feet away from him, later told NBC that he had been "trying not to really even look at him" and that he had been thinking about "nothing."
A number of blasts in various touristic areas in southern Thailand killed four people and wounded many more Thursday and Friday. People in Thailand and around the world took to social media to express solidarity with the victims and the country, using the hashtag.
Unlike previous years, when Thailand-related hashtags were celebratory, since Aug. 12 marks two special occasions for the country, the Queen's birthday and Mother's Day, this year, Thailand wasn't trending in a positive way. Hashtags like #Explosion and #StrongerTogether were also trending in the country following the attacks.
Aug. 12 also marked International Youth Day, a celebration set by the U.N. to recognize the ideas and efforts of young people around the world.
The theme this year is “The Road to 2030: Eradicating Poverty and Achieving Sustainable Consumption and Production.”
This year’s celebration is about turning the 2030 Agenda for Sustainable Development into reality.
U.N. Secretary-General Ban Ki-moon left a video message shared by the UN4Youth Twitter account. Here it is:
Katie Ledecky is a 19-year-old U.S. swimmer, yet her Olympic achievements weigh a lifetime of success.
Ledecky left Rio with four gold medals, including three in individual events, as well as a silver medal as part of the 400-meter freestyle relay.
Ledecky's third individual gold medal in the women’s 800-meter freestyle was the fruit of one of the most impressive individual performances at the 2016 Olympics Friday night. She won in a world record-breaking time of 8:04.79, and the internet was sure to recognize it.
