上 [shàng]

v.  To ascend. A sexist term meaning “to jump [someone]”, usually used by men to describe “to have sex with someone in a fast and disrespectful way.”

Du Fu: A row of white egrets ascends the blue sky (qīng  tiān).

Bao Zheng (dubbed “bāo  qīng  tiān“): Darn it! You…

[Note: Du Fu is a renowned poet in the Tang Dynasty. “A row of white egrets ascends the blue sky” is cited in his poem “A Quatrain.” Bao Zheng is a famous judge in the Song Dynasty. He was touted as “Qingtian” (blue sky) because of his integrity and uprightness—as transparent as the blue sky. In this joke, he got upset about the Du Fu’s quote because the word  “ascends” is interpreted as the Internet slang term that means “to fuck.”]
