我太南了

Meaning

"Jī nǐ tài měi" (鸡你太美/Chicken you're so beautiful) is a mondegreen of "只因你太美" (Only because you're beautiful) from Cai Xukun's "Idol Producer" audition. His self-intro combined basketball and dance—the moment he threw away the ball and started dancing awkwardly to "只因你太美 baby" became hilarious. Netizens heard "只因" as "鸡" (chicken), sarcastically saying "Chicken you're really so beautiful" to mock him.
