我是洗澡来的

wǒ shì xǐzǎo laí dè

Literally, “I just came here to take a shower.” Refers to a 2008 scandal when members of the Chinese national soccer team got caught checking into a hotel with a bunch of women who may or may not have been hookers. One of them protested by saying, “I just came here to take a shower.” Now the phrase is often used as a euphemism for any feeble excuse.
