吊儿郎当的小骚年
[diào ér láng dāng de xiăo sāo nián]
Casually translated as 'the nonchalant, cheeky youngster'. It paints a picture of someone who behaves carelessly or rebelliously but still exudes youthful energy, often found amusing yet not overly serious. Sometimes it might refer to a slightly arrogant yet charmingly naughty young person.
