Idiot: Barney, it looks like you are getting a little round around the middle *poke*.
Barney: No, you idiot, that is my fuel tank. It is how I pwn you so hard when it comes to fucking hot girls and on the water!

The Fuel Tank 4 is ultra fast, steamrolling past the competition.

fuel-tank 

After having anal sex and ejaculating, the male keeps his penis inside the female's rectum until it gets flacid, then he proceeds to fill the ass with urine.

She said, "Fill me up!" so I fuel-tanked the bitch.

Since it's hard to pee when your dick's hard, you'll have to give it a moment to soften up before a good fuel-tanking session can take place.

fuel injection 

"A process in which fuel is supplied to an engine via a pump, nozzles, and a computerized control module. This system has mostly replaced the carburetor, a much simpler mechanical device found in any car worth owning."

Person 1: "Fuel Injection is so much more reliable than carburetors."

Person 2: "Uhh, okay. Is that why your car has been to the shop three times and the 'check engine' light is still on?"

Person 1: "It was just a bad sensor."

Person 2: "How much did it cost to fix?"

Person 1: "$238."

Person 2: "I could replace the entire fuel system on my car for $238."

Person 1: "But..."

Person 2: "No."

Person 1: "I was..."

Person 2: "NO! YOU WILL BOW DOWN BEFORE THE ALMIGHTY 1972 LINCOLN CONTINENTAL! (holds lincoln keychain in face)

Person 1: "AAAAH! IT BURNS!"

Person 2: "THE POWER OF GOD COMPELLS YOU!

Person 1: "NOOO! (black vomit) (convulsions)

Person 2: "Damn, you must've worked at a dealership."

Person 1: " '75 LTD coupe convertible?"

Person 2: "Now you're talking."

Fuel Cell 

Beyond and better than Diesel. If someone's Fuel Cell towards you, they like you more than a friend.

See Girlfriend or Boyfriend.

Whoa, you're big pimpin', Enrique! Those girls are definitely being fuel cell towards you. If I used your tactics without practice, they'd turn gasoline in a matter of seconds!

2.) I sure hope my neighbors have a fuel mule because when the shit hits the fan I'm fucked.
