When two men stand in front of each other, face to face, with their two erect penises almost touching. Their Jap's eyes are alligned so they are staring directly at each other. Once in the right position the men start masturbating their own penis until one of them ejaculates. The first one to ejaculate into the other ones Jap's eye wins the contest.
Luke: How about a Japanese staring contest Zak?
Zak: I would like that very much Luke!
While in a fight, the last resort. A Japanese Catapult involves running at your opponent at full speed and about 6 feet before you hit him/her tuck into a cannonball with your head between your legs. Often used by the weaker ones in society such as nerds, gay people, and Ghandi.
Jorge knew he had to make a bold move when he got knocked to the ground by the jock's punch. So he pulled himself up, charged at him and tucked into a Japanese Catapult....... Jorge missed and slammed into a brick wall, shattering 3 of his ribs.
