one thumb up 

this is seen when someone has made a really really bad defintion or defined a word that really need not be defined but feels so alone in the world and doent want to seem unpopular so they VOTE FOR THEIR OWN DEFINITION. this results in a mear 1 THUMB UP and makes them look better. it is also obvios to the common joe that people who do this arent that smart in the noggin as they would make themselves look much better if they voted for it MORE THAN ONCE!

One Inch Punch 

In Jeet Kune Do one has four fighting distances: Kicking range, punching range, trapping range and grappling range. Very few Martial Arts have these many. Usually they only have 2 or 3 ranges. The one inch punch is used in the trapping range. In trapping range you are too close for a kick and too close for a western boxing punch. It's short and very explosive and it doesn't have to be "loaded" to make damage. One needs to train very hard to get it right. I have been training Jeet kune do for about four years now and I say its about speed and timing.

The act of having sex. It has its roots in a 50 cent song.
