欧巴等等我
[ōu bā dĕng dĕng wŏ]
In Korean popular culture, 'oppa' (often transliterated as 'ouba') means 'brother' but it also has affectionate usage beyond just familial relations. So, this phrase 'oppa wait for me' conveys longing and admiration from a fan towards someone admired, possibly inspired by K-pop fandoms.
