KakaoTalk
A Korean app that lets you chat with people and send stupid emojis. It's like being in a fight with your friends and your mom all at once.
My teacher sent me a message that said 'Do your homework or I'll send you to the principal.'
My crush said 'Hey' and I replied with 100 heart emojis.
My mom sent me a duck emoji and a message that said 'You're still ugly.'
