In My Humble (Honest) Opinion, as in "Speaking IMHO" - A disclaimer of sorts, used on blogs, message boards, forums etc.; used to clarify that the statement being made should not be quoted as a fact, but only as an opinion.
1) Speaking IMHO, I think everyone should have a job of some sort.
2) IMHO, you are a looser.
3) IMHO, this is the best answer.
4) Freedom of speech is Speaking IMHO
Supposedly "in my humble opinion", this is always said before someone makes an asshole comment that is not at all humble. Much like "no offense" precedes an offensive comment.
