火星文 (huǒxīng wén): Martian script
Mars script (sometimes called brain damaged script [ 脑残体 ]) is a form of coded Chinese writing that uses abbreviations, homophones, Roman letters, and other nonstandard characters. For instance, “don’t mention it,” (不要说 bú yào shuō) is shortened to biǎo shuō (表说) and the word “thank you” becomes 3q (sān q). A free Chinese-to-Martian converter app is available on Baidu from I Love Martian Script (我爱火星文). See Wikipedia for origins and usage.
ex. The Song of the Grass-Mud Horse in Martian script:
Original
在那苍茫美丽马勒戈壁有一群草泥马
他们活泼又聪明
他们调皮又灵敏
他们由自在生活在那草泥马戈壁
他们顽强勇敢克服艰苦环境
噢卧槽的草泥马
噢狂槽的草泥马
他们为了卧草不被吃掉打败了河蟹
河蟹从此消失草泥马戈壁

English
There is a herd of grass-mud horses
In the wild and beautiful Mahler Desert
They are lively and intelligent
they are fun-loving and nimble
They live freely in the Mahler Desert
They are courageous, tenacious, and overcome the difficult environment
Oh, crouching grass-mud horse
Oh, crazy grass-mud horse
To protect their grassland, they battled the river crabs
River crabs are forever banished from Mahler Desert
