Como dizer "ser trapaceado" em inglês

I agree with Donay. The Dictionary.com definition is consistent with what I have heard and read

It will help to understand the meaning if you associate "to be had" with the strong Portuguese word "f*der". "To be had" is a slang way to say "to have sex", but in a negative, cynical way. It is not vulgar, but it is informal English. It is easy to see how "to be had" came to mean "to be cheated, fooled, swindled, taken advantage of, etc."

First some homework: The symbol for the prevention of forest fires in the USA is a bear. They call him "Smokey the Bear", and he wears a wide brim hat like the Boy Scouts, some police forces, etc. The bear's hat is called a "Smokey the Bear hat". Yes, there are other names for it such as "campaign hat, drill instructor hat", and so on. Jumping to Ireland, the "Limerick" is a simple poem with a rhyming pattern of AABBA. The last line is funny and is usually a big surprise. Most Limericks are somewhat vulgar, but not the one below! Ready now?

A woman once had an affair
With a man all covered with hair
When he reached for his hat
She realized that
She had been had by Smokey the Bear

Many (usually funny) Limericks can be found on Google.
