Humiliation: a state of reduced lowliness brought on by mistreatment be it intentional or accidental. The results of said humiliation can range from humorous to devastating. A slip of the tongue for instance can cause GREAT humiliation with devastating results. Then let that slip of the tongue be brushed over like it never happened, no apology or anything because the speaker was probably praying no one heard the slip yet knowing full well everyone present did. Everyone. Including the person it humiliated and the person who gloried at the slip. Not a simple ill spoken word but a complete "how in the hell did you say what you just said" ill spoken word. Despite the old rhyme "sticks  and stones" WORDS hurt bitterly. Think before speaking. THINK. If thinking is a challenge then don't speak.
                               Humorous slips are usually caught right away by everyone in hearing distance and followed by a riotous fit of laughter. The speaker might be slightly humiliated but no harm is inflicted on anyone. Just a sheepish oops with the correct statement uttered while still laughing. No harm no foul.
