长肉这种事有种冲胸来Y
[zhăng ròu zhè zhŏng shì yŏu zhŏng chōng xiōng lái y]
The username uses a humorous play-on-words expressing frustration at weight gain, focusing on gaining weight in specific body areas, such as around the chest area. Here '有种冲胸来Y' can be loosely translated as 'if it's gonna come anywhere let it come straight to the front (meaning chest)' with a hint of internet slang.
