Sucker

The internet slang term “sucker” is used to refer to a person who is easily fooled, naive, or gullible. It is often used in a teasing or mocking manner to make fun of someone’s lack of knowledge or ability to see through deception.

Examples:

1. John thought he won a free trip to Hawaii, but it turned out to be a scam. His friends called him a sucker for falling for such an obvious trick.

2. Sarah believed a stranger’s email claiming she had won a million dollars. After sharing her personal information, she realized it was a phishing scam. Her brother couldn’t help but laugh and say, “You’re such a sucker, Sarah!”
