东皇太一般
[dōng huáng tài yī bān]
Not quite accurate as it sounds confusing to foreigner, it means Donghuang Taiyi is one character in the ancient chinese myths which stands for power and supremacy, but when saying '东皇太一般' it may mean this user consider him/herself just so-so like the emperor of all emperors is not so special. Here shows self-denial and some kind of humor.
