我是你的疯婆子
[wŏ shì nĭ de fēng pó zi]
'I am your mad woman' implies strong bond between speaker ('I') and listener ('your'). Here 'Mad' refers both craziness out of love and bold unrestrained spirit beyond conventional limits. 'Bpozi'(Chinese Internet slang) often used endearingly by young couples. Thus overall, expressing unconditional support/obsession towards certain people, showcasing passionate, sometimes obsessive side with touch of self-mockery.
