Bridge it twelve is the fundamental concept of Hung Gar. It's a connection between you and the other person and you facilitate control over your opponent. Usually, in either attack or defense. There are twelve bridges: hard bridge, soft bridge, crowding bridge, direct bridge, dividing bridge, stabilizing bridge, inch bridge, lift bridge, sending bridge, controlling bridge, settling bridge, and flow/reverse bridge. This is mainly used in Kung Fu.
Novice: Master, teach me each component of bridge it twelve, so I can become the best Kung Fu fighter in the whole world

Master: This will take a considerable amount of time, but is necessary in order to dominate every opponent you will face.

Screwing something up right at the last second when everything seems in hand; choking at the worst possible time in the worst possible way. This stems from the ambulance mission in the video game GTA III, which has twelve levels and takes forever and is hard and random and makes you want to throw things when a person you are trying to rescue on level 12 spawns inside a sidewalk and cannot move or runs into your ambulance and kills himself causing you to fail the mission and lose all that time and have to start over. Douching a twelve means to fail the mission on the final level, which, trust me, is just the worst.
Man, did you see that race? The leader really douched a twelve on the last turn right there!

Dude, you got this. Do NOT douche a twelve right here.
