In modeling, it refers to the state of exhibiting intense fierceness with one's face and body during a photo shoot. One who does not exhibit tension can be said to resemble a "limp noodle". It quickly became a favorite term of supermodel Tyra Banks on the twelfth cycle of America's Next Top Model, much to everyone's annoyance.
Tension is uncomfortable situations like riding away on a moto butt naked and loving it. It is tripping over infront of cops on purpose and just all out the stupidest shit you could think off. Its also a video done by the east coast boys on there bodyboards.
Tommo: have you seen the movie tension
Ben: yeah man how funny is it they do the best tensions.
