delulu

This is short for delusional and became a smear word ten years ago in K-Pop for obsessive fans who really thought that their idol would fall in love with them and marry them.  It can still be used as a synonym for  ‘totally divorced from reality’ but be careful.  Its meaning has shifted so that now it can be a synonym for ‘excellent’.   It can  mean that you are sensational, full of chutzpah and behaving in a way that is outrageously full of confidence and style. It has followed the path of manic which originally meant wild and hysterical but then became a term of praise for a performance that was over the top.  And insane which meant ‘mad’ but could also mean ‘fantastically wonderful’. So delulu has gone from being a derogatory description to being a term of praise.
