没人牵手我兜裤兜
[méi rén qiān shŏu wŏ dōu kù dōu]
'No One Holding Hands, So I Put Hands in My Pocket' playfully refers to loneliness where there's nobody around for physical affection like holding hands. Instead, they resort to putting their hands in pockets, which can also symbolize a casual way to handle solitude.
