猫街少女梦鲸镇少年情
[māo jiē shăo nǚ mèng jīng zhèn shăo nián qíng]
'The Girl from Cat Street Dreaming of Whale Town’s Young Affections'. 'Cat Street' could mean a narrow, quiet alley, or a district where the owner used to live and raised cats; 'Whale Town', alternatively is a made-up place. So this username expresses an affectionate, innocent feeling towards someone from another specific place in adolescence.
