"Nigerian princes" refers to a common internet scam where fraudsters pose as wealthy individuals, often claiming to be royalty from Nigeria. They typically send unsolicited emails or messages, promising large sums of money in exchange for assistance in transferring funds out of the country. These scams exploit the recipient's trust and often ask for personal information or upfront fees. The term has become synonymous with online fraud, highlighting the need for caution when receiving unexpected communications that seem too good to be true.
