暑假被走我请你吃炫迈
[shŭ jiă bèi zŏu wŏ qĭng nĭ chī xuàn mài]
This nickname combines elements of nostalgia and casualness. '暑假' refers to summer vacation, a carefree time for most students, while '炫迈' is a brand of gum, often associated with something cool or flashy in China. The phrase '被走我请你吃' doesn't form coherent grammar here; thus, it seems playful and non-traditional, possibly reflecting the creator's wish to treat friends during holiday.
