"屎壳郎" (shǐ ké láng) is a Chinese expression that means something like "dung beetle." The term is often used to refer to someone who is considered to be useless or unimportant.

The origin of the term is unclear, but it may come from the fact that dung beetles feed on feces, which is considered to be a low and dirty job in many cultures. The term may also be used to refer to someone who is considered to be a "scavenger" or "bottom feeder" in society.

Here are some example sentences using the term in English:

"Don't be a shǐ ké láng – get out there and make something of yourself!"

"The boss always treats him like a shǐ ké láng – he never gives him any real responsibility."

"She's such a shǐ ké láng – she just sits around all day and does nothing."

Here are the corresponding translations in Chinese:

"不要做个屎壳郎，去追求你的梦想吧！"

"老板总是把他当做屎壳郎，从不给他真正的责任。"

"她就是个屎壳郎，整天无所事事。"
