My family speaks cantonese but I had a spanish baby sitter growing up, so I often mixed the two languages together. For example, I used to play the video game of Richard Scarry's Busy, Busy Town. You had to get around the different parts of the map using the applecopter. So when I played it with my dad, I would point it out using "manzana feigei" which is literally "apple plane" using spanish and cantonese repsectively. My dad at the time went "What the fuck did you just say?"
