青年拉好你的裤链姑娘闭好你的双腿
[qīng nián lā hăo nĭ de kù liàn gū niáng bì hăo nĭ de shuāng tuĭ]
'Youth, Pull Up Your Pants; Girls, Keep Your Legs Closed.' This carries an advisory meaning, possibly cautionary advice to young individuals to respect social norms about sexual activities. However, it can be considered provocative depending on context.
