"But that really doesn't do shit. (Source: baozouribao.com)

Short for "but it really can't do shit" (rán'ér bingbìng méiyǒu shénme luǎnyòng 然而并没有什么卵用); conveys something's uselessness or a situation's hopelessness. Catchphrase from the comedy show Baozou Big News (Bàozǒu Dà Shìjiàn 暴走大事件).

"Can't do shit" was popularized in the summer of 2015 on the sketch comedy show Baozou Big News. In a mock interview, the character Zhang Quandan (张全蛋), a quality inspector at Foxconn, talks about the many functions of the cell phones being manufactured:

It has so, so many functions Like it can remotely control your home's air conditioning And also it can help you get on your neighbor's wifi And then remotely control your neighbor's air conditioning And also it can help you hack into your local server And remotely control the air conditioning on an entire block But that really doesn't do shit

它的功能非常非常的many 比如它能遥控你家的空调啊 再比如它能帮你连上隔壁的wifi 然后遥控隔壁家的空调啊 再比如它能帮你hacker到小区的服务器里 并且遥控一整条街的空调 然而并没有什么卵用
