ok the actual definition of "OMFB" is "oh my franking bob". it got started (as far as i know) on theblackparade.net, as an alternative to "OMFG" that some MCR fans enjoy saying. also "OMFG" can also mean (for frerard supporters/MCR fans in general) "oh my franking gerard" and "OMG is of course "oh my gee/gerard". so...yeah. thats wat it means deal with it.
OMFB is that guy over there looking at me???? OMG!!!!!

Acronym that means "Oh my fucking Buddha."

Simular to OMFG except with a B instead of a G.
A more extreme version of OMB.

The term you use when you forgot to check Facebook (FB) or your "social network" when something somewhat dramatic was posted... and you totally missed it.

Oh My Fat Bitch... Basically I got tired of saying OMFG and we know what it means. It's offensive and people yell at me for using it. So I found something else a little less geared toward religion and something everyone loves to talk about. Fat B-Otches. OMFB allows for a comfortable laugh here an there when speaking. It also can be used in offensive/defensive situations where skinny people or less fatter people may be attacked.
OMFB are you really wearing that? OMFB are you really going to eat that? I can't stand this, OMFB. Or simply OMFB (If you happen to see a mean fat girl.)
