IMNSMFHO 

Abbreviation of In My Not So Mother Fucking Honest Opinion. It is a variation on IMHO (In My Honest Opinion), used in situations where you want to be sarcastic.

You see a stick figure anorexic bitch walking down the road. Taking a picture with your mobile you send it along with this message to your mate Stephen:
"Damn, Check out this girl with sum fat titties, IMNSMFHO! LOL!"
