呀土豆你个马铃薯呀番茄你个西红柿
[yā tŭ dòu nĭ gè mă líng shŭ yā fān qié nĭ gè xī hóng shì]
This playful and humorous phrase literally compares potatoes to spuds and tomatoes to tomatoes, essentially calling someone or referring to oneself by alternative names in a teasing way—a casual, fun, nonsensical expression.
