shot bum 

The seat behind the driver in the car. The seat beside the driver is shotgun. The seat behind the shotgun is cobain.

Shotgun is the best seat in a car because you have a dominant position and the best view and more leg room. However, if the driver is short and has the seat pulled forward, shot bum can have more leg room than shotgun or cobain, who will be ready to blow his brains out because he has no leg room.

Bif- "Shotgun."

Skippy - "Dude, I called it like 3 minutes ago."

Bif - Okay, I want shot bum then because Kelly has the seat all the way forward.

Matt - I guess that means I get cobain

Bumshot 

An extremely unfortunate final moment during the climax of one's porn-accompanied masturbation session, in which the viewer of said pornography experiences their orgasm at the exact same time the cameraman gets an all-inclusive shot of the guy's ass for a solid 5-10 seconds

Guy 1: "Hey man, you don't look so well. You doing alright?"
Guy 2: "Dude, I just had the most humiliating bumshot..."
Guy 1: "Jesus...that's just bad luck, man."

Bumshot 

The Bumshot originated from Kyoto, Japan in 1998 and was invented by Kevin Rockushima. It is now the most common form of smoking cannabis throughout East Asia and Northern Australia and is immensely popular in the Hip Hop scene.

How it works:
You insert a marijuana cigarette (or joint) backwards into your anus. The person you wish to bumshot must then cup their hands over their mouth, nose and the back end of the marijuana cigarette. When you're ready to discharge intestinal gas, notify the person you're bumshotting to inhale deeply. You must now break wind gently.
Although not proven scientifically, the smoke from a bumshot is said to be up to five times more potent than smoking marijuana directly.

Warning:
Bumshotting can be dangerous and must only be performed by trained individuals using specially designed bumshot technology and supporting literature.
Inserting marijuana cigarettes directly into the anus can cause internal burns if not done correctly.
Intestinal gases can be highly flammable in some cases, therefore you must always have a fire extinguisher to hand whilst bumshotting. The Bumshottee must also wear fire retardant clothing and protective eyewear.
Bumshotting must not be performed by sufferers of chronic diarrhoea.

Famous users of the bumshot method:

Will Smith (rapper, actor)
Kevin Smith (Silent Bob)
Snoop Dogg (rapper)
Richard Gere (actor)
Yokosuma (wrestler)
Tina Turner (singer)
Al Pacino (actor)
Kevin Spacey (actor)
Paris Hilton (solicalite)
David Bowie (singer)

I like to bumshot.
Bumshotting is not just a filthy habit, it's a way of life!
I am a bumshottee and have frequently been bumshotted by a bumshotter during sexual intercourse.
