纯属娱乐纯属戏弄
[chún shŭ yú lè chún shŭ xì nòng]
The phrase means something is done purely for amusement or jest. 'For Entertainment Purposes Only' sums up this Chinese name well in English. Here it suggests an intent free of seriousness, only aiming at having some fun without intending real effects, such as making a humorous joke.
