君生我亦老
[jūn shēng wŏ yì lăo]
The literal translation of this Chinese phrase goes: 'When you were born, even I grew old.' In essence, this nickname expresses feelings of age differences between the user and someone significant to them - whether they're talking about a crush, love interest, admired idol etc. More likely, it carries sorrow over losing youthful vigor or unreciprocated feelings due to age difference.
