《柯林斯英汉双解大词典》中，对godfather offer给出了如下释义：

godfather offer

a takeover bid pitched so high that the management of the target company is unable to dissuade shareholders from accepting it 无法拒绝的高额公司兼并要约

虽然中文释义为“无法拒绝的高额公司兼并要约”，并未查到相关的中文表达，但在investopedia中查到了相关的英文释义：

A Godfather offer is an irrefutable takeover bid made to a target company by an acquirer. Typically, the offer is priced at an extremely generous premium compared with the target's prevailing share price, making it difficult for management to reject the bid without angering shareholders and being accused of breaching their fiduciary duty.

A Godfather offer is named after the Francis Ford Coppola movie of the same title. More specifically, the name refers to the film's famous line, "I'm gonna make him an offer he can't refuse." This line has gone on to become one of the most celebrated quotations in cinema.

由上可看出，Godfather offer来源电影Godfather，尽管无“无法拒绝的高额公司兼并要约”的相关中文释义的使用，从英文释义来看，确实是要表达的这个含义，理解上还可以参考如下案例：

Example of a Godfather Offer

Company A is a promising, up-and-coming developer of new, niche technologies. Its solutions could revolutionize how the world operates, leading some larger companies to sniff around and inquire about taking it over.

Company A's management team privately rebuffs all proposals, claiming it has no interest in selling and handing over all its potential to another firm. That strategy helps to keep the predators at bay for a few months until one of them turns hostile.

Company C, an industry juggernaut with significant financial resources, eventually gets tired of Company A's reluctance and responds by tabling a generous Godfather offer directly to shareholders. A bid of $70 per share is lodged, representing a 75% premium on Company A's current market price.

Company A's board is livid and maintains it does't want to sell at any cost, while the shareholders it is elected to represent voice support for the deal and refuse to take no for an answer. Suddenly, things turn messy. Disgruntled shareholders engage in a proxy fight, joining forces in an attempt to seize control and get the takeover approved. They also threaten to sue senior management for failing to act in their best interests.

A公司是一个有前途的、新兴的、利基技术的开发商。它的解决方案可以彻底改变世界的运作方式，导致一些大公司闻风而动，询问是否要收购它。

A公司的管理团队私下里回绝了所有的提议，声称它没有兴趣出售并把所有的潜力交给另一家公司。这一策略有助于在几个月内将掠夺者挡在门外，直到他们中的一个变成敌对者。

C公司是一个拥有大量财政资源的行业巨头，最终厌倦了A公司的不情愿，直接向股东提出了慷慨的教父式报价。出价为每股70美元，比A公司目前的市场价格高出75%。

A公司的董事会很生气，坚持认为它不想不惜一切代价出售，而它所代表的股东则表示支持这项交易，并拒绝接受拒绝的答案。突然间，事情变得很混乱。不满的股东参与了代理权争夺战，联合起来试图夺取控制权并使收购获得批准。他们还威胁要起诉高级管理层，因为他们没有按照自己的最佳利益行事。
