爱的真操的深
[ài de zhēn cāo de shēn]
The phrase 'Ai de zhen cao de shen' sounds like 'true love penetrates deeply', implying deep and genuine feelings. However, the way it's phrased is a colloquial mix of formal and vulgar terms which could also be translated humorously or shockingly in other contexts. It conveys the intensity and depth of true love, as felt or idealized.
