Do you sometimes have a hard time understanding what Americans are talking about among themselves? Do
you want to know why? The answer is, Americans are crazy about using slang. They tend to over do it, though.
Otherwise, slang is fun to use. You should try it. And some slang is easy to understand. For example, if
someone is "off the hook," it means that he is no longer in trouble. The "hook" is a fish hook. If a fish is
on the hook, of course, it is in trouble. If it is "off the hook," then it is out of danger. Didn't we tell
you slang is fun? Besides, it should at least help you feel more at home and not like a fish out of water
when you speak to Americans.
