SFB

Acronym for SHIT FOR BRAINS.

A descriptor for stupid people and people who either do not think or lack a capacity to think.

A total idiot.
Example 1:
That SFB over there is picking a fight with a cop. I bet he wins a Darwin Award.

Example 2:

Pilot:
Seatack Air traffic control, this is N50669 and I need a landing clearance now. I can n o longer maintain a holding pattern. I am getting a five minute warning on my fuel gauges.

Air Traffic Controller:
N50669, maintain holding pattern until advised to land.

Pilot:
Seatack Air Traffic Control, What is your malfunction SFB? I am 30 seconds into a five minute warning light on my fuel gauges Either you give me a clearance now or I am putting this bird down on top of another airliner because in about four minuets I will be graivity's bitch.

Air Traffic Controller:
N50669, you do not have landing clearance.

Pilot:
Air Traffic Control, Listen SFB, I am at 3 minuets and thirty seconds and counting as I am running out of fuel. I am on approach and the two of us can discuss this malfunction face to face when I land this bird. I am declaring an emergency landing so make way because daddy is coming home!

Example 3:
Your dog is so stupid you should have named him SFB.

What does that mean?

You dog has Shit For Brains.
