"甲亢哥"和"大妈"是两个中文词汇，分别指的是甲状腺功能亢进的男性患者和中年女性。而"外星人"则是一个英文词汇，指的是来自外星生物的人。 所以，"甲亢哥和大妈合影被美颜拍成外星人"这句话的意思是：一个患有甲状腺功能亢进的男性（甲亢哥）和一个中年女性（大妈）在合影时，被一种美颜功能拍摄后，看起来就像是外星生物一样。。
甲亢哥和大妈合影被美颜拍成外星人英文可以简单翻译为："甲亢哥" and "大妈" are two terms used in Chinese to refer to someone with hyperthyroidism, which is an overactive thyroid gland. In the translation of "甲亢哥和大妈合影被美颜拍成外星人," it can be translated as: "The brother with hyperthyroidism (甲亢哥) and the elder lady (大妈) were photographed together, but their photo was edited by a beauty app to look like extraterrestrial beings."

The phrase "were photographed together" means that they were taken a picture together. "was edited by a beauty app" indicates that the photo was edited using a beauty or photo-editing app, such as Snapseed or Adobe Lightroom. "to look like extraterrestrial beings" means that the photo has been altered to make them appear like extraterrestrial beings.。

简单的来说这个问题涉及到了两个不同的概念：甲亢和美颜。 首先，甲亢是一种甲状腺功能亢进的疾病，会导致身体代谢过快，出现一系列症状，如心悸、失眠、多汗等。 其次，美颜是一种通过各种技术手段来美化照片的技术。 将甲亢患者和大妈合影被拍成外星人，可能意味着这张照片经过美颜处理，使得甲亢患者的脸部特征与普通人有所不同，看起来像是外星人。这可能是因为美颜技术会改变照片中人物的面部特征，使得原本不具有明显特征的人变得与众不同。 总的来说，这个问题主要是在描述一种情况，即甲亢患者在进行合影时，由于美颜技术的处理，使得他的脸部特征与普通人有所不同，看起来像是外星人。
