OK, so people from Korea and Japan have been sharing videos of themselves balancing their phones on their boobs/pecs for about a week.
They're doing this because of an anime video that was uploaded to YouTube last week before being taken down for violating the site's community practices. It has since been re-uploaded, but it's still kinda sexual and is based on a lot of illustrations of girls with huge boobs.
After the video went viral, Korean Twitter began emulating one of the characters by balancing their phones and tablets on their chests.
Japanese Twitter then took notice and began using the hashtag #tawawachallenge to share videos of themselves balancing their phones on their chest.
Soon after women began sharing videos, men did too.
And people got more and more creative.
Some people uploaded videos that didn't even have phones in them.
The whole thing is a bit of fun, really. Which is nice, because sometimes the internet should be fun.
