The abbreviation “IMHO” (In My Humble Opinion) covers only a part of cases when the writer/speaker expresses his own point of view, which may not correspond to the opinion of “general public”. In the What style of costumes for Halloween? forum thread using IMHO did not “suit” the situation.

Thus a new term was born: IMPO – In My Perverted (or Perversive) Opinion.

See the difference? ;-)
