Finally a challenge I can agree with!
There's a new trend where women and voluptuous men are squeezing their boob into the shape of a heart. It started in China but it's going viral worldwide now.
You form a heart shape with your hands, then kinda jam your boob through.
And if you're thinking, "Oh, maybe they're doing this to raise awareness for breast cancer" or something like that -nope. It's just boob squishing for boob squishing's sake.
