An acronym for "In My Humble Opinion", which is ironic since any use of the term indicates that a statement is undeniable truth, and that anyone that disagrees is either insane or a fucktard.
Extremely condescending. Pronounced "Im-Ho", or possibly "I'm a ho".
Since everything said on the internet (even facts) is opinion, IMHO is completely redundant and should never be used.
- IMO - A more humble version of IMHO. Used exactly the same way, with exactly the same meaning.
