[字彙] 一個字典查不到的字

[tenghui (PERFECT CRANK)]

剛剛看了FRIENDS第九季的第十集，

裡面一開始Joey和Phoebe的對話如下：

P: "I'm sorry. It's just, I'm little short on cash."

J: "If your want, I could loan you some money."

P: "Oh, no. I learned never to borrow money from friends.
    That's why Richard Dreyfuss and I don't speak anymore."

J: "Why don't you just spunge off your boyfried?"

其中我想問的就是這個"spunge off"，字典上找不到

看了字幕的中文翻譯，整句的翻譯是"妳幹嘛不跟妳男朋友拿錢呢？"

請問一下這個字的正確意思為何？又用法大致上為何呢？謝謝～
