我是超人苏坡面
[wŏ shì chāo rén sū pō miàn]
It's more like a personal nickname or a humorous phrase. From its structure, it may refer to the person sees himself as a superhero, and probably because he is very good at something, maybe cooking noodles called 'Su Po Mian', making it his trademark skill. It shows individuality and uniqueness.
