Question

請問 she was about to can me是什麼意思 ?
原文如下 :
How to break up with a guy

Don’t let him be the last to know

Sure, talking through your feelings with a friend can be helpful when working up the courage to break things off, but try to limit yourself to how many people hear the test-run of your dumping speech. Eventually, some one is going to blab, and as any guy will tell you, being the last to know that you’ve been dumped is not fun. “My best friend told me that he heard my girlfriend was thinking of breaking up with me,” says Dave, 32, from Long Island, NY. “I later found out that all of my friends knew before I did. I was so pissed off and humiliated. I felt like the biggest fool on earth, walking around telling every one how in love I was, and all of them knowing she was about to can me. It was the worst.”

11. Slang. to dismiss; fire.
12. Slang. to throw (something) away.

13. Slang. to put a stop to: Can that noise!

謝謝ㄚ傑，也謝謝其他各位的回答。

Answer 1

can還有"解雇"的意思

所以在這裡She was about to can me.
就是說她將要把我解雇了
就是說她要把我甩了的意思.

其他應該不用翻譯吧?

Answer 2

要連前面的文也一起看.....

and all of them knowing she was about to can me.
而所有的人都知道她想要跟我分手。

或是更前面....

I felt like the biggest fool on earth, walking around telling every one how in love I was, and all of them knowing she was about to can me.
我感覺我就像是地球上最笨的笨蛋，到處跟別人說我們兩個是多麼的相愛，但所有的人都知道她其實想要跟我分手。
