A more thorough explanation:

Definition: Feemail (fee-mayl) is a slang term used to describe an attorney's fee that is obtained through intimidation, threats, or pressure. It can also refer to the act of extorting such a fee. This is similar to blackmail, graymail, and greenmail.

• After the trial, the lawyer demanded a feemail from his client, threatening to reveal confidential information if he didn't pay up.
• The opposing counsel engaged in feemail by threatening to drag out the case and make it more expensive if we didn't settle.

These examples illustrate how feemail is a form of extortion used by lawyers to obtain more money from their clients. It is unethical and illegal, and can result in serious consequences for the attorney involved.
