On Tuesday, Indian boxer Vikas Krishan gave his fans a reason to cheer by beginning his Olympic campaign on a winning note. He beat United States' Charles Conwell with a dominant victory of 3-0 to enter the pre-quarterfinals of the men's middleweight (75kg) category at the ongoing Rio Olympics 2016.

Adding to the optimism, the Indian men's hockey team beat Argentina 2-1 in a crucial match, enhancing its chances of making the quarterfinas.

While Indians were applauding these events, there's what social media users in other parts of the world were commenting about.

The attack of the #PhelpsFace

Sporting a hooded jacket and headphones, swimmer Michael Phelps’ facial expression has gone on to inspire humorous memes on Twitter.

The most decorated Olympian of all time has perfected the epic death stare. The 31-year-old Olympic legend can now add "internet meme" to his long list of accomplishments.

Behold, a parody account has already been birthed from the look that broke the internet.

The great Canadian chest bump fail

Two of the best athletes in the world muffed up a simple chest bump. It happened when the Canadian men's volleyball team came back from seeming defeat to beat their Brazilian hosts. To celebrate a victory, Canadian men's volleyball team members, Ben Saxton and Chaim Schalk, went in for a chest bump – and failed.

Redditors are loving the the slow motion GIF which has gone viral. According to user 24Gospel, "Looks like they were going in for an open mouth kiss, until they remembered they are on international TV." And here is oprangerop's opinion: "A full on make out session would had looked less awkward then this."

Here is the stuff that epic fails are made of.

#OlympicSongs

The Olympic committee is notoriously protective and is known for threatening to sue anyone they think is infringing its intellectual property rights. Since that restricts the playing of the Olympic theme song, Twitterati are creating their own #OlympicSongs.

Here are few to be played to pump up the adrenaline.

Parents at the Olympics

Nothing is more nerve-racking than stepping upto the bar as a gymnast competing in the Olympics. Except for, maybe, being a parent of that competitor. United Sates gymnast Alexandra Rose Raisman's parents have been providing hilariously awkward moments at the Olympics.

The Olympic gold-medalist's parents have been known for their painful reactions and nervous energy, ducking and cringing while their daughter competes. Their showcasing of tension in the intensity of the moment has made them a favourite with the internet.

Chinese strokes

Chinese Olympic swimmer Fu Yuanhui has become a sensation on the Chinese social media circuit after she finished third in the women’s 100m backstroke in Rio de Janeiro on August 7. More than for her swimming skills, the internet is loving the 20-year-old athlete for her dramatic expressions.

The sincere swimmer couldn't believe she had placed third. "58.95 seconds!? I thought it was 59 seconds!" Yuanhui reacted when a reporter gave her the good news. "Whoooaah! I was so fast!"

Green swimming poo(l)

On Tuesday, a swimming pool turned green. Not just a light green but a bright radioactive-toxic looking kind green. This happened ahead of the 10-meter women’s synchronised platform final.

The Rio Olympics’ official Twitter account tweeted out that the water had been tested and posed no risk for athletes. However, a further investigation is underway.
