fabarrassing
When someone is so fat and so embarrassing they make you want to hide under a bed and never come out.
My dad tried to do a dance at my mom's birthday party and fell into a cake. He looked like a messy cake monster.
My sister tried to do a karaoke song and sang it wrong. The whole restaurant laughed at her.
My friend tried to do a YouTube live and his dog ran into the camera. It was like a chaos livestream.
