采蘑菇的草泥馬
[căi mó gū de căo ní mă]
'采蘑菇的草泥马' can be interpreted as 'Grass Mud Horse Picking Mushrooms'. Here ‘草泥马’ (grass mud horse) is often used as a homophonic euphemism on the Internet, adding a bit of lighthearted playfulness. In general, someone might choose such a humorous nickname out of fun and to show a down-to-earth personality when facing trivial tasks.
