大哥，是不在外国过的不错？

As for those keen fans with tunnel visions, I suggest you reply in English and show us what you've got from him.

我在英美呆了这么多年，身边随便一个人英语都好百倍，也就是没见过世面的山村小孩崇拜他，接着走火入魔吧。
After spending so many years first in Britain and then in America, I dare say that anyone, I mean literally anyone I've worked with so far, speaks English hundredfold better. Only those born and bred in the impoverished mountainous rural areas of China find him an object of admiration, a bunch of pathetic cult members, who would give anything to stay in the grip of obsession.

I met him two years ago

都什么年代了？还有一些没文化没见过世面的 “邪教徒”，人云亦云地吹牛你们主子会 "同声翻译"，你们被洗脑了，先搞清什么是同声翻译再来吹牛吧。
It is surprising, in this day and age, that there are some boorish, insular “cult members” still making a big fanfare about his ability to do "simultaneous interpretation“. You follow him like sheep and have been brain-washed. You may as well get the concept of "simultaneous interpretation” first before coming back to brag again, boneheads.

大哥，帮我教训一个人。此人自称英语天下第一，我们本事不够，没法揭穿他。还望大哥出山给他点颜色看看
