[tŭ dòu nĭ gè fān qié jiàng fān qié nĭ gè mă líng shŭ]
Playing with the names for potatoes and tomatoes in English, calling a potato by the sauce made from tomatoes and vise versa, it humorously refers to things getting confused or mixed up. Possibly indicating the user's playful, casual or quirky personality.
