恬不知耻的愚蠢
[tián bù zhī chĭ de yú chŭn]
'Tian Bu Zhi Chi De Yu Chun' roughly translates as 'Shameless Stupidity.' It portrays the characteristic being unabashed by stupidity or foolishness. Someone uses this net name perhaps in the form of ironic confession about own shortcomings, indicating an admission or acceptance of failure, and possibly even laughing at themselves.
