In medicine, especially in obstetrics or genetics, an abbreviation for "Father Of the Baby."

Slightly slang when said as a word, "fob," which suggests that it is not known if he is the baby's mother's husband. A slightly more respectful way of saying "baby daddy."
The patient would like the F.O.B. to be in the room during the delivery.

She's a single mother with six children and four fobs.

It has two definitions: a) an abbreviation to a band (Fall Out Boy) or b) an abbreviated curse (Fuck Off Bitch)
a) "Thanks for the Memories" is by FOB.

b) "FOB!"

fob = Fresh Off the Boat.

This word is used on people who pretend to know what they're talking about, or who act as if they don't notice others are around them. it's usually used as an insult, though sometimes people will name themselves fobs.
Person 1: Hey, what's new?
Fob: Lyk3 OMG! How could you ask such a stupid question?
Person 1: Wow. You're such a fob.
Fob: Excuse me? What the -expleted- is a FOB? Does fob stand for FABULOUS? You know it does.

A abbreviation for the term 'Found On Boat'. Commonly used in a derogatory manner towards people of Maori or Samoan descent, who immigrate into other countries. FOBs are known to be outcasts, both fashion-wise and language-wise. They generally group together with their own kind to perform such activities as playing basketball (or b-ball) and rapping.
"Look at those lousy FOBs playing basketball"
"Stupid rapping FOBs"
