Very uncommonly used abbreviation meaning "Fuck Off My Messenger", not to be onfused with FOML ("Fuck Off My Lawn"), it is definitely of internet-only usage.

FOMFB

Fool on My Facebook. Someone who posts stupid or inflammatory comments on your Facebook wall. A person who tries to throw down on Facebook. Usually a stranger IRL.

Dude, this FOMFB got all up in my shit and kept posting smack on my FB wall. I had to delete his ass.
