I won't bite = 我不会欺负你。。。 比如， A: 可以站的离我远一点吗？ B: 干嘛？我又不会干什么！ A: Could you not stand so close to me please? B: What? I won't bite! 那当然也有的人会倒过来说，我“会”欺负你 = I WILL bite! I will bite...我只能想出一个用法，(不知道你是否指这个) 那就是。。。在别人给你暗示时可用的， 比如： A向B说（但她装自言自语）: 今天真糟糕！ A says to B (But pretends she is talking to herself): I've had such a bad day! 明明想让B问她怎么了。 It's obvious she wants B to ask her what's up. 在这种情况下B就可以说： B: 好啊， 我问吧。。。怎么了？ In this case, B can say: B: OK, i'll bite...what's up? 为什么说“i'll bite”呢？ 因为A的话就像鱼饵一样， 等着B(一条鱼) 来咬 （bite） So why do we say "I'll bite"? Because A's words were like bait, waiting for B (the fish) to bite.

我会咬你。。
