孤独狗

'Dan Du Gou'. This translates to 'Lonely dog', but has nuances. Rather than just lonely, in Chinese context '孤' could imply independent, alone not necessarily badly affected by solitude. So it's not solely negative; sometimes self-deprecating way show personality embracing individuality despite social disconnection aspects emphasized here. Users might feel marginalized, but comfortable enough in their own skin acknowledging single status humorously.
