When you pack as many people as possible into a mini van, with enough weed as you can get and all start smoking at once. the ratio of people to smoking paraphernalia should 2:1, but more joints, bowls, bongs, and hookahs never hurts. The point of the submarine is not to be moving but to find a safe spot and fish bowl it so bad that you take a hit just by taking a breath and make it hard to see in from the out side from all the smoke.

Side note: Always remember to bring food and drinks in the van before you start smoking
the smoke was so thick when we went submarineing last weekend, that you literally couldn't see your hand one foot in front of your face

To be attacked by surprise. To be set up. Ambushed.
My coworker submarined my today! We sat down for an hour to discuss how to solve the problem and came up with a solution. Then, when we met with the boss and he didn't seem all that wild about "my" solution, my coworked simply nodded his head in agreement with the boss's comments and stared at me blankely as though he didn't know what I was talking about.

Similiar to Motor Boating, only submarining involves a really loose girl so that you can effectively motorboat her cooch.

A sexual act involving a man eating out a woman's vagina while masturbating. Just before the man cums he looks up at her and when she notices him looking at her he says "Target locked". While the girl is still in confusion he says "Fire Torpedo!" as he jumps up and cums in her face. Then walks away saying "Target Destroyed"
"Kellsi was so surprised when I gave her that submarine for her birthday"

Being online on a web messenger service but appearing as if you were offline.
Ash: "Are you submarining again?"

Cynthia: "Yes, I don't want to be bothered by all of my contacts, so I answer only those I want to talk to."

The act of ripping a bongload then chugging a beer before exhaling the smoke.
Dude did you see that guy at the party do a submarine and pass out on the floor? Classic.
